Evaluate (2-3)*(4) - 9 = 3.

-13≠3

Step-by-step explanation:

(2-3)*(4)-9=3

first do the things in parenthesis (2-3)=-1

then multiply both parenthesis (-1)*(4)=-4

then subtract -4-9= -13

-13≠3

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

ok then what happened.
