Answer:2/8?
Step-by-step explanation:
Answer:
<h2>AB = 38</h2><h2 />
Step-by-step explanation:
|<----------------- AB ------------------->|
A--------------------M--------------------B
5x + 4 3+16
since M is at midpoint, AM = MB
5x + 4 = 3 + 16
5x = 3 + 16 - 4
x = 15 / 5
x = 3
AB = AM + MB
AB = 5(3) + 4 + 3 + 16
AB = 15 + 23
AB = 38
2x +100=16+4x
-2x. -2x
100=16+2x
-16. -16
84=2x
divide both sides
x=42
