Answer:

Step-by-step explanation:

(g•f)(2) = g(f(2))

Since f(x) = 5x - 4

f(2) = 5(2) - 4 = 10 - 4 = 6

(g•f)(2) = g(f(2))

g(f(2)) = g(6) = (6)^2 = 36

Step-by-step explanation:

set F function in g function:

gof(x) = (5x-4)2

simplified:

gof(x) = 10x-8

put 2 in function

gof(2) = 10(2) - 8 => 20-8 => 12

These shapes are geometric, which means they're equal. XW would be the same as XY, which is 18. The same goes towards WZ. WZ = ZY, so it'll be 29. Remember, since it's geometric, each side has to equal each other
