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.

part a

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
