6x−3

18x−3

18x - 9

Step-by-step explanation:

Factor the common factor of 9 first which gives

is the difference of two squares and factors into (2x + 1)(2x - 1)

The complete factorization of is 9(2x + 1)(2x - 1).  

So 9(2x - 1) = 18x - 9 is a factor of the original expression.

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)

the option best identifies the textual evidence that supports this conclusion is c.) when an argument is over, how many weighty reasons does a man recollect which his heat and violence made him utterly forget? in order to recognize textual evidence is to identify the topic sentence where the author states the main idea. textual evidence is what supports the topic sentence or main idea of a passage.
