Answer:
7x³ + 9x² - 3x - 8
Step-by-step explanation:
4x³ + 6x² + 2x - 3 + 3x³ + 3x² - 5x - 5 ← collect like terms
= 7x³ + 9x² - 3x - 8
F(g(x)) where you see an 'x' in f(x) put a g:
f(g(x)) = 1/(g-7), now step by step: g - 7 = 6/x+7-7=6/x, and 1/(g-7)=1/(6/x)=x/6!
I let the second one for you. Sorry if you disagree!
