Answer 1

15

Answer 2

The answer is two thirds but I confused with the steps.

Answer 3

me to

Answer 4

[(2 - 8) / (X+4)] / [(3 - 12) / (X+4)]
= [-6 / (X+4)] / [-9 / (X+4)]
= [-6 / (X+4)] * [(X+4) / -9]
The (x+4)s cancal out, so you have
-6/-9
= 2/3

Answer 5

Answer 10

Answer 12

[8/(x+4)] * 8x
= 64x / (x+4)[8/(x+4)] * 8x
