To factor 9x2-4, you can first rewrite the expression as:
a. (3x - 2)²
b. (x)² – (23²
c. (32)2-(2)
d. none of the above

In this question, you would need to factor the expression in order to figure out how you can rewrite it.

You would be factoring:

Factor:

When you factor, you would notice that you could represent the expression as (3x+2)(3x-2)

You would notice that (3x+2)(3x-2) is not an answer choice.

Therefore, your answer would be D). None of the above​, because the answer that you get when you factor is not a answer choice.

answer: 45

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
