If h(x) = 2x and k(x) = 2x - 4, what is h(k(x))?

To find h(k(x)), substitute k(x) into h(x):

h(k(x)) = 2x

          = 2(2x - 4)

          = 4x - 8

Thus, h(k(x)) = 4x - 8 would be your final answer.

d. 9

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
