Answer: First we evaluate g(0), then plug the value into f(x).
g(0) = -2(0) + 7 = 7.
Thus, we need to do f(7).
f(7) = 3(7)-4 = 21 - 4 = 17.
Step-by-step explanation: Hope it helped :)
Perimeter = 140
Side 1 = x
Side 2 = 2x
Side 3 = 3x - 10
x + 2x + 3x - 10 = 140
6x - 10 = 140
6x = 150
x = 25
Side 1 = 25 cm
Side 2 = 50 cm
Side 3 = 65 cm
Hope this helps!! :)
