(Question 2) I put down 10x=20 then did 10x/10=20/10 then got x=2, what do I do with the M

m just means measure. it’s not a variable. you also did your math wrong.

Step-by-step explanation:

it’s tells you that angle ABC is 60°. so the correct equation would be 20+10x=60, and then you would subtract 20 from both sides and get 10x=40. then you divide to get x=4.

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
