This is on my assesment so please answer

Part A: 10

Part B: 6.25

Step-by-step explanation:

The perimeter is the length + width + length + width. in this case -> 2.5 + 2.5 + 2.5 + 2.5 or 2.5 * 4

The area can be found by length * width or in this case -> 2.5 * 2.5

24

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
