To make things easier, we can assume a value of x in order to substitute to each expression and obtain the side length of each. We can calculate for perimeter of each square. Then, compare them. We do as follows:

Assume x = 4
Square A
2x - 7 = 2(4) - 7 = 1
P = 4(1) = 4

Square B
-4x + 18 = -4(4) + 18 = 2
P = 4(2) = 8

Therefore, the perimeter of B is 2 than the perimeter of A.

The functions r and s are defined as follows.
irina1246 [14]

Answer:

r(s(-2)) = -2

Step-by-step explanation:

We are given these following functions:

r(x) = -2x + 2

s(x) = x^2 - 2

Find the value of r(s (-2)).

First we find the composition of r and s functions. It is:

r(s(x)) = r(x^2-2) = -2(x^2-2) + 2 = -2x^2 + 6

At x = -2

r(s(-2)) = -2(-2)^2 + 6 = -8 + 6 = -2

r(s(-2)) = -2
