Answer:

- 66

Step-by-step explanation:

Evaluate g(- 4) then substitute the value obtained into f(x) , that is

g(- 4) = - 2(- 4)² = - 2 × 16 = - 32, then

f(- 32) = 2(- 32 - 1) = 2 × - 33 = - 66

Choose 2 hellllpppppp plzzzxxxxzz

diamong [38]

Answer:

Choices C and D

Step-by-step explanation:

The most simplest way is just to solve each one and see which two have the same answer as the first expression.

But you could also see that both of the $\frac{4}{7}$ are going to cancel each other out so you are left with $-\frac{8}{9} +\frac{9}{8}$ which is also choice C.

For choice D I distributed the negative one to the insides of the parenthesis that left me with $-\frac{4}{7}-\frac{8}{9}+\frac{4}{7} +\frac{9}{8}$ which is the same expression as the first one.
