Answer: -36
Step-by-step explanation:
To evaluate the expression, you want to plug in r to solve.
-40(-31-16(-2))²+(-2)² [parenthesis]
-40(1)²+(-2)² [exponent]
-40+4 [add]
-36
Now we know the expression is equal to -36 when r=-2.

OD. (x - 5)(x - 5) + 10(x - 5)
Please someone help me this texts is so important and I need it done by the end of today!
Answer:
B
Step-by-step explanation:
Expand (x+5)^2 through binomial expansion and you get x^2+10x+25.
Break up the problem into little pieces like (x-5)(x+5) and 10(x+5)
Solve the first piece (x-5)(x+5) by doing something like FOIL.
x^2-25
Do the second piece
10x+50
When you add them together, it becomes x^2+10x+25, and (x+5)^2=(x-5)(x+5)+10(x+5).

Given point (-6, -2) and a slope of 5, write an equation in slope-intercept form.
Answer:
y = 5x + 28
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5 , thus
y = 5x + c ← is the partial equation
To find c substitute (- 6, - 2) into the partial equation
- 2 = - 30 + c ⇒ c = - 2 + 30 = 28
y = 5x + 28 ← equation of line

what does 52 belong to?natural,rational,integer,whole ?
Answer:
The number 52 is a rational number if 52 can be expressed as a ratio, as in rational. A quotient is the result you get when you divide one number by another number. For 52 to be a rational number, the quotient of two integers must equal 52. ... Thus, the answer to the question "Is 52 a rational number?" is YES.

Solve 12 + 12a + 4a = -4
Answer:
a=-1
Step-by-step explanation:
we need to get a by itself
first combine like terms

now we need to get rid of the 12 so subtract it to other side
-16=16a
now divide 16 by -16 which gives you -1=a

What are the next two terms in the sequence?
5, 16, 27, 38 ...
Answer:
the next two terms are 49, 60
Answer:
49, 60
Step-by-step explanation:
There is a common difference between consecutive terms in the sequence.
16 - 5 = 27 - 16 = 38 - 27 = 11
Thus to obtain the next term, add 11 to the previous term, that is
38 + 11 = 49
49 + 11 = 60

If each interior angle of a regular polygon is 144 degrees. Find the number of sides in it.
Answer:
10
Step-by-step explanation:
In a polygon
interior angle + interior angle = 180°, thus
exterior angle = 180° - 144° = 36°
The sum of the exterior angles in a polygon = 360°, thus
number of sides = [tex]\frac{360}{36}[/tex] = 10
Answer:
10 sides
Step-by-step explanation:
A decagon is a 10-sided polygon, with 10 interior angles, and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles. Each angle measures 144° and they all add up to 1,440°.
h(x) = 3x + 3
g(x)=-4x + 1
Find (h+ g)(10)
How to solve this ?
Answer:
h(x ) = 3 x+ 3
g ( x ) = − 4 x + 1
( h +g ) ( x ) = 3 x + 3 − 4 x + 1 = − x + 4
( h + g ) ( 10 )
= − 10 + 4
= − 6

Answer:
2/8, 4/16, and so on
Step-by-step explanation:
1/4 could be equal to many numbers as long as when you simplify it down it will reach 1/4
Answer:
2/8
Step-by-step explanation:
There are many fractions which are equaivalent ( equal ) to 1/4 such as 2/8
This is because when you reduce 2/8 to its lowest terms it becomes 1/4.

To mail a package, UPS charges a $7 flat fee and $2 per pound. FedEx charges
a $5 flat fee and $3 per pound.
Answer:
The package where they charge the same must cost $2
Step-by-step explanation:
Given
UPS
[tex]Flat = \$7[/tex]
[tex]Additional = \$2/lb[/tex]
FedEx
[tex]Flat = \$5[/tex]
[tex]Additional = \$3/lb[/tex]
Required
What pound do both charges are the same
Represent the charges with x;
For UPS, it can be written as:
[tex]Charges = 7 +2x[/tex]
For FedEx:
It is:
[tex]Charges = 5 + 3x[/tex]
Equate these charges together
[tex]5 + 3x = 7 + 2x[/tex]
Collect Like Terms
[tex]3x - 2x = 7 - 5[/tex]
[tex]x = 2[/tex]
Hence, the package where they charge the same must cost $2

A flowchart proof : 1).contains a set of sentences explaining the steps needed to reach a conclusion. 2).uses inductive reasoning to prove a statement. 3).uses a visual representation of the logical flow of steps needed to reach a conclusion. 4).contains a table with a logical series of statements and reasons that reach a conclusion.
Answer:
3) uses a visual representation of the logical flow of steps needed to reach a conclusion.
Step-by-step explanation:
I took the test.
Flow charts gives a graphical or pictorial representation of the sequential steps which should be followed to solve a given problem.
Flow charts are similar to algorithms in that they provide a stepwise approach to solving a problem or reaching a conclusion on a particular task. However, flow charts reflect presents the sequence of operation in a graphical of pictorial format.
Therefore, flowcharts uses a visual representation of the logical flow of steps needed to reach a conclusion.

Answer:
lim(x---->0) = -5
Step-by-step explanation:
first: sin(x-π/2)= -cosx
so the equation will be :
