Answer:
Step-by-step explanation:
Use ratios to find x and y, then find AB and GH, them sum up the lengths.
<u>Find x:</u>
- 12/15 = x/10
- x = 12*10/15
- x = 8 in
<u>Find y:</u>
- 12/15 = 16/y
- y = 15*16/12
- y = 20 in
<u>Find AB:</u>
<u>Find GH:</u>
<u>Find the perimeter:</u>
- P = 6 + 15 + 20 + 10 + 37 + 8 + 16 + 12 = 124 in

Alexis needs to score at least 96 points on her next test in order to have an average of at least 90.
explanation:
85+89+92+96= 360
359/4=90
Minus the 10 from the 50, which makes 40. then divide 40 by 8
50-10=40
40÷8=5
n=5
