Can sum 1 simplify these for me they are easy worth 20 pts

Hi There!

Remember to follow PEMDAS.

Question #1:

12 - 6 ÷ 2 · 3 + 4

= 12 - 3 · 3 + 4

= 12 - 9 + 4

= 3 + 4

= 7

Question #2:

(-6/5)³

-6/5 = -1.2

= -1.2³

= -1.728 or -216/125

Question #3:

³√729

= 9

Hope This Helps :)

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
