Given f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).

f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).

Replace f(x) and g(x) with their given values:

h(x) = -2x + 4x -8

Combine like terms:

h(x) = 2x -8

this is answer of 144 cubic meters

i think it might be a but you might want a second opinion
