Answer 1

Hi Liz, add up all of the x terms and then add up all of the number only terns and you have the answer. Then it is necessary to simplify.

9x - 4 + 4x + 5x + 19

x terms:

9x + 4x + 5x = 18x

Number terms:

-4 + 19 = 15

Together:

18x + 15

What is the greatest common factor:

3 will divide into both 18 and 15, leaving 6x + 5.

Answer:

3(6x + 5)

Correct choice:

A
