Solve
x^2/2=8
4x=16/x

S = {4,3.2}

Step-by-step explanation:

x^2/2=8

x^2=8*2

x^2=16

x=(sqrt)16

x= 4

4x=16/x (multiply x)

5x=16

x = 3.2

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
