(6a + 6) + (3x - 2) + (2a + 4)

8a+8+3x

Step-by-step explanation:

Just plus them! Nothing so harsh

6a + 6 + 3x-2 + 2a +4=

= 6a +2a+3x+6-2+4=

= 8a+3x+8

Step-by-step explanation:

1. remove the () since the actions within them cannot be solved.

2.find the sum

c. (3,2,6) is the answer.

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
