Answer:
8cx - 22ac - 15bx + 45ab +18ax - 6bc.
Step-by-step explanation:
(8c-9b)(x-5a)+(3x+3c)(6a-2b)
= 8c (x-5a) -9b(x-5a) + 3x(6a-2b) + 3c(6a-2b)
= 8cx - 40ac -9bx + 45ab + 18ax - 6bx + 18ac - 6bc
Combining like terms:
= 8cx - 22ac - 15bx + 45ab +18ax - 6bc.
Answer:
8cx + 45ab + 18ax - 2bc - 15bx - 22ac
Step-by-step explanation:
(8c - 9b)(x - 5a) + (3x + 3c)(6a - 2b)8cx - 9bx - 40ac + 45ab + 18ax + 18ac - 6bx - 2bc8cx + 45ab + 18ax - 2bc - 15bx - 22acFind the area of the parallelogram
Answer:
A = 3484 ft²
Step-by-step explanation:
Area of a parallelogram is given by the formula:
A = bh (where b is the base length and h is the vertical height)
Substituting values given in the diagram gives us:
A = 67×52
A = 3484
Units will be ft² since it is area.
So our final answer is 3484 ft²

Answer:
x = -6 and x = 1
Step-by-step explanation:
For the fraction to be undefined, find the zeros of the polynomial of the denominator.
x² + 5x - 6 = 0x² - x + 6x - 6 = 0x(x - 1) + 6(x - 1) = 0(x + 6)(x - 1) = 0x = -6 and x = 1What is the area of the parallelogram?

answer to the nearest hundredth.
Answer:
x = 45.79°
Step-by-step explanation:
You can use sin Θ to find the value of x.
Let us find it now.
Sin x = Opposite / Hypotenuse
Sin x = 38 / 53
Sin x = 0.7169
x = Sin ⁻¹ 0.7169
x = 45.79°

Given g(x)=xpower of 2-6x-16,which statement is true?
For the given function g(x)=xpower of 2-6x-16, the statement which is true, is the zeros are -2 and 8 because the factor of g are (x+2) and (x-8).
What is a quadratic function?A quadratic function is the function in which the unknown variable is one and the highest power of the unknown variable is two.
The standard form of the quadratic function is,
[tex]f(x)=ax^2+bx+c[/tex]
Here,(a,b, c) is the real numbers and (x) is the variable.
The quadratic function given in the problem is,
[tex]g(x)=x^2-6x+16[/tex]
Factorized it with split the middle term method,
[tex]g(x)=x^2-6x-16\\g(x)=x^2-8x+2x-16\\g(x)=x(x-8)+2(x-8)\\g(x)=(x-8)(x+2)[/tex]

algebra elimination- 13x+8y=-2 and 2x+y=-1
Answer:
x=-6/29
y=-17/29
Step-by-step explanation:
we have the system of equations
-13x+8y=-2 ------> equation 1
2x+y=-1 ------> equation 2
Solve by elimination
step 1
Multiply equation 2 by -8 on both sides
-8[2x+y=-1 ] ---------> -16x-8y=8 ------> equation 3
step 2
Adds equation 1 and equation 3
-13x+8y=-2
-16x-8y=8
-----------------
-29x=6
x=-6/29
Find out the value of y
substitute the value of x in any equation
2x+y=-1
2(-6/29)+y=-1
-12/29+y=-1
y=-1+(12/29)
y=-17/29
therefore
The answer is
x=-6/29
y=-17/29

Jessica has $40 to spend at the book fair. She buys 2 notebooks for $3 8. each and wants to spend the rest of her money on books. How many books can Jessica buy if each book costs $8? How much money does Jessica have left over?
Answer:
She can buy 4 books
Step-by-step explanation:
If each notebook is $3, and she bought two, she'd be left with $32 because 40-6=32. Simply multiply 8 by 4 to get 32, which is the rest of her money. Hope this helps!

Hello people ~
factorise : 3x² + 10x + 8
Answer:
(x + 2)(3x + 4)
Step-by-step explanation:
3x² + 10x + 8
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × 8 = 24 and sum = + 10
the factors are + 6 and + 4
use these factors to split the x- term
3x² + 6x + 4x + 8 ( factor first/second and third/fourth terms )
= 3x(x + 2) + 4(x + 2) ← factor out (x + 2) from each term
= (x + 2)(3x + 4) ← in factored form
[tex]\\ \rm\Rrightarrow 3x^2+10x+8[/tex]
[tex]\\ \rm\Rrightarrow 3x^2+6x+4x+8[/tex]

Step-by-step explanation:
Covert the mixed fractions into improper fractions to make this easier.
2 [tex]\frac{1}{4} and 3\frac{1}{2}[/tex] into [tex]\frac{9}{4} (2*4 +1) and \frac{7}{2} (3*2+1)[/tex]. (In parenthesis, its the process of creating the improper fractions and not part of the fractions themselves.
Now you just multiply both together since 1 bag needs 2 1/4 kilograms and Anthony needs 3 1/2 bags.
That gets you [tex]\frac{63}{8}[/tex] which you get by multiplying 9 and 7 in the numerator and 4 and 2 in the denominator
Finally, find out how many 8 goes into 63 which would be 7 times. 63-(7*8) = 7.
And so the answer is 7 7/8
Bella has 7 more dimes than nickels, for a total value of $1.45. If n represents the number of nickels, what equation could be used to find the number of nickels Bella has?
Answer:
15 nickels
Step-by-step explanation:
so you know she has 7 dimes so youre starting off at .70
how much money would it take to get from .70 to 1.45?
.75 cents to get from .70 to 1.45 which is 15 nickels
Answer:
0.15n + 0.70 = 1.45
5 nickels
Step-by-step explanation:
Nickel = 5 cents = $0.05
Dime = 10 cents = $0.10
Let n = number of nickels
Let d = number of dimes
Given:
Bella has 7 more dimes than nickelsTotal value of $1.45Equation 1: 0.05n + 0.10d = 1.45
Equation 2: d = n + 7
Substitute Equation 2 into Equation 1 and solve for n:
⇒ 0.05n + 0.10(n + 7) = 1.45
⇒ 0.05n + 0.10n + 0.70 = 1.45
⇒ 0.15n + 0.70 = 1.45
⇒ 0.15n = 0.75
⇒ n = 5
Therefore, Bella had 5 nickels and 12 dimes.

How much should be invested at 7% compounded daily for 15 years to make $200,000?
The amount of money that should be invested at 7% compounded daily is $199,421.68.
How to calculate compound interest.Mathematically, compound interest is given by this formula:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
Where:
A is the future value.P is the principal.R is the interest rate.T is the time measured in years.n is the number of times compounded.Given the following data:
Future value = $200,000.
Interest rate = 7% = 0.07.
Time = 15 year.
Substituting the given parameters into the formula, we have;
[tex]200000=P(1+\frac{0.07}{365} )^{ 15}\\\\200000=P(1+0.00019)^{15}\\\\200000=P(1.00019)^{15}\\\\200000=1.0029P\\\\P=\frac{200000}{1.0029}[/tex]

Name Guided Practice DO Do You Understand? 1. If the orchard has 200 seedlings and 12 are planted in each row, how many rows will be filled? Draw place-value blocks to show your answer. In Problem 1. what does the remainder I don't get how 200 is 16
Answer:
16 rows, 8 seedlings left.
Step-by-step explanation:
Divide 200 by 12, since 200 seedlings are going to be split in 12 groups in order to fill the rows.
200 ÷ 12 = 16 with a remainder of 8.
The remainder is basically what is left.
Since 12 seedlings are planted in each row, 8 seedlings is not enough to completely fill the row. So, the answer is 16 rows with 8 seedlings left.

The area of the stacked prism is the amount of space on it
To create a total area between 100 square inches and 130 square inches, 2 to 2.5 prisms
How to determine the number of prisms?
The dimension of the prism is given as:
2 inches by 3 inches by 4 inches
The surface area of the prism is calculated as:
A = 2 * (LW + WH + LH)
This gives
A = 2 * (2 * 3 + 3 * 4 + 2 * 4)
Evaluate the product
A = 52
When the prisims are stacked onto one another, the surface area is between 100 square inches and 130 square inches.
So, the number of prisms (n) needed is:
100/ 52 < n < 130/52
Evaluate the quotient
1.9 < n < 2.5
Approximate
2 < n < 2.5
Hence, 2 to 2.5 prisms are needed to create a total area between 100 square inches and 130 square inches.
