Question

Please help I really need this grade to pass the quarter

Answer 1

AB = 8

Explanation:

you have to set up a ratio. AE = 6 because 15-9=6. which means the ratio is 6:9. Simplify it to get 2:3. 13/3 = 4

4x2 = 8

Answer 2

8

Explanation:

AB=x

AE is 15-9=6

x/6=(12+x)/15

Multiply both sides by 30

5x=2(12+x)

5x= 24 +2x

3x=24

x=8
