Answer:
-1/2
Step-by-step explanation:
first, we multiply 2 and -5 which is -10, then we multiply 5 and 4 which is 20
so, we get -10/20 then the simplest form is -1/2

I don’t know how to do this -2(-5+n)=6 ?
Answer:
n = 2
Step-by-step explanation:
So all you have to do is solve:
-2(-5 + n) = 6
= 10 + -2n = 6
= -2n = -4
= n = 2
This means that n = 2.
But what if I'm wrong? So lets see if it works.
-2(-5 + 2) = 6
10 - 4 = 6
6 = 6
So n = 2 is right.
Hope this helped! :D
Answer:
n = 2Step-by-step explanation:
I don’t know how to do this -2(-5+n)=6 ?
-2*(-5+n)=6
10 -2n = 6
10 - 6 = 2n
4 = 2n
2 = n
-----------------
check
-2 ( -5 * 2) = 6
10 - 4 = 6
6 = 6
3) A closed rectangular box with volume 12 cubic feet is such that the length of its base is twice
the width. Express the surface area of the box as a function of the width.
Point Breakdown

2) 6 points
3) 6 points
A closed rectangular box with volume 12 cubic feet is such that the length of its base is twice the width.The surface area of the box as a function of the width is (4b³ +36)/b.
volume 12 cubic feet
volume =(l)(b)(h)=12
l=2b
(2b)(b)(h)=12
h=6/b²
Surface area = 2 (lb + bh + lh)
= 2((2b)(b) + b(6/b²) + 2b(6/b²))
=4b² + 12/b + 24/b
= (4b³ +36)/b
A three-dimensional object's surface area is the sum of all of its faces. Real-world applications of the notion of surface areas include wrapping, painting, and finally constructing things to get the greatest potential design.
An object's surface area is the total area that all of its surfaces occupy. The formulae we will learn in this post make it simple to determine the various surface areas that various 3D forms in geometry have. There are two groups for the surface area:
The surface area that is laterally oriented or curved

8. Gavin goes to the market and buys one rectangle shaped board. The
length of the board is 16 cm and width of board is 10 cm. If he wants to add
a 2 cm wooden border around the board, what will be the area of the
rectangle board?
160 cm² is the area of the rectangle.
What do we mean by rectangles?A rectangle is a closed two-dimensional shape with four sides, four corners, and four right angles (90°). A rectangle's opposite sides are equal and parallel. Because a rectangle is a 2-D shape, it has two dimensions: length and width. The word rectangle is derived from the Latin word rectus, which means "right" or "straight." A rectangle has straight sides due to its right angles.Rectitude, which means moral uprightness, is another word with the same root.The formula for the area of a rectangle:
l × bPut values in the formula:
= 16 × 10= 160 cm²Therefore, the area of a rectangle is 160 cm².

determine a series of transformations that would map polygon abcd onto polygon a'b'c'd
Answer: a reflection across the y-axis and scaling it by a factor of 1/2
Step-by-step explanation: First, you need to reflect the shape over the y-axis to move it into the neighboring quadrant. After that, you scale the polygon down by a factor of 1/2, because the lengths of the line segments of A'B'C'D' are half the length of the original polygon, ABCD.
How much larger is 3/4 than 2/3
Answer:
3/4 = 0.75 2/3 = 0.6667 Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.75 is greater than 0.6667 which also means that 3/4 is greater than 2/3.
Step-by-step explanation:
B is between A and C. If
AB=x+4 , BC=2x−2 , and AC=4x−1 , what is AB?
AB= (geometry someone help)
If B is between A and C and AB= x+4,BC= 2x-2 and AC= 4x-1, then the length of the AB is 3 units
The point B is between A and C
AB = x+4
BC = 2x-2
AC = 4x-1
We know,
AC = AB + BC
Substitute the value in the equation and find the value of x
4x-1 = x+4 + 2x-2
4x-1 = 3x-2
4x-3x = -2+1
x = -1
Then,
AB= x+4
Substitute the value of x in the equation
AB = -1+4
AB = 3 units
Hence, If B is between A and C and AB= x+4,BC= 2x-2 and AC= 4x-1, then the length of the AB is 3 units

Equivalent equations are algebraic equations that have identical solutions or roots.
Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.
Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
The first step is to know the rules of equivalent equations:
Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation.
Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
Raising both sides of the equation to the same odd power or taking the same odd root will produce an equivalent equation.
If both sides of an equation are non-negative, raising both sides of an equation to the same even power or taking the same even root will give an equivalent equation.

Help!! Find the domain of the graphed function.
Help please .
I can’t figure out magnitude . Can anyone help me ASAP ?
Answer:
|-20| |12.3| |8| |-6| |-4| |2 3/10|
Step-by-step explanation:
Magnitude in this context means that they want you to order the values from greatest to least. These are all absolute values and that means distance from zero without regard to sign. So if you just stripped the signs and absolute value symbols off of each value, then ordered them from largest to smallest, and THEN added the signs and absolute value symbols back, you have the answer.
Answer:
From greatest to least magnitude
|-20|
|12.3|
|8|
|-6|
|-4|
[tex]\lvert {2 \frac{3}{10}}\rvert[/tex]
Step-by-step explanation:
The absolute value of a number |x| is the positive value of x. So if x is positive then it's the number itself and if x is negative it is the positive value of the number
Ex. |5| = 5 and |-5| = 5
Take the absolute values of each of the numbers first
|12.3| = 12.3
|-20| = 20
|2 3/10 | = 2 3/10 = 23/10 = 2.3
|-4| = 4
|8| = 8
|-6| = 6
Now arrange these numbers from greatest to least. The order is
20, 12.3, 8, 6, 4, 2.3
So in terms of the original numbers this corresponds to
|-20| , |12.3| , |8|, |-6| , |-4| , |2 3/10|

Function yes or no whag is the domain and range?
Step-by-step explanation:
to be a function every value of x must have exactly one value of y.
in other words, if you create a vertical line and move it across the whole chart (e.g. from left to right), this line must not even once intersect the function curve more or less than once.
so, this is clearly a given here. yes, it is a function.
the domain is the interval or set of all valid x (input) values. and that starts on the right with x = 5 (included in the function indicated by the filled dot). and it goes endlessly to the left. that means -infinity (but not included as "infinity" is only a symbol but not a number).
-infinity < x <= 5
the range is the interval or set of all valid y (function result) values.
and that starts on the top with y = 2 (included). and it goes endlessly down. that means again -infinity (not included).
-infinity < y <= 2

A parking lot is shaped like a parallelogram and bounded on four sides by streets, as shown in the figure to the right. How much asphalt (in square yards) is needed to pave the parking lot?
The amount of asphalt needed to pave the parking lot is __ yd^3, yd, or yd^2
Amount of Asphalt needed = 27000 square yards
The shape of the parking lot is a parallelogram.
In the figure, the base of the parking lot is of length 180 yd and the height of the parking lot is 150 yd.
If 'b' is the base of the parallelogram and 'h' its height, then area of the parallelogram, A = bh
So here, base length, b = 180 yd
and height, h = 150 yd.
Therefore, area of the parking lot which is parallelogram, A = bh
= 180 x 150
= 27000 yd² (square yards)
Amount of Asphalt needed to pave the parking lot = Area of the parking lot
= 27000 square yards

Taking into account the scientific notation, the result of the sum is 5.64×10⁻⁹.
Scientific notationScientific notation is a quick way to represent a number using powers of base ten.
The numbers are written as a product:
a×10ⁿ
where:
a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.n is an integer, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it is shifted to the left, negative if it is shifted to the right.Sum in scientific notationTo add two numbers in scientific notation, when the numbers to be added do not have the same base 10 exponent, the base 10 power with the highest exponent must be found. In this case, the highest exponent is -9.
Then all the values are expressed as a function of the base 10 exponent with the highest exponent. In this case: 7.4×10⁻¹⁰= 0.74×10⁻⁹
Taking the quantities to the same exponent, all you have to do is add what was previously called the number "a". In this case:
4.9×10⁻⁹ + 0.74×10⁻⁹= (4.9 + 0.74)×10⁻⁹= 5.64×10⁻⁹
Finally, the result of the sum is 5.64×10⁻⁹.
