2(8 x 4) + 2(4 x 10) + 2(8 x 10)

Step-by-step explanation:

the expression represents the surface area, because it is finding the area of the three different sizes of sides, doubling them, then adding them together

d is correct

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
