A. 32x - 45
B. 8x + 45
C. 32x - 30
D. 8x - 45

Answer 1

First you need to distribute 5(4x-6) what would that expand to?

Answer 2

20x - 30x
or is that the wrong way ?

Answer 3

Close. It would be 20x-30 do you see this?

Answer 4

oh i didnt mean to put the x in 30

Answer 5

Ok now that you distributed it what would the equation above look like if we substitute (20x -30) for 5(4x-6)?

Answer 6

20x - 30 + 12x - 15

Answer 7

Correct..now combine the like terms and you have simplified

Answer 8

so 20x - 12x + 30 - 15 ??

Answer 9

Actually 20x-12x-30-15...

Combine the like terms..combine all the x terms and all the constant terms..so it would be
20x-12x = 8x
-30 -15 = 15

So we have 8x-45

Answer 10

Test is saying its 32x - 45
