Answer:
AB = 8x+10
Step-by-step explanation:
If M is the midpoint of the segment AB, then AM+MB = AB. Given the following parameters;
AM=9x-5 and MB=15-x
Required parameter
segemnt AB
Substituting the given parameters into the given formula to get AB we will have;
AB = AM+MB
AB = 9x-5+15-x
collect like terms
AB = 9x-x-5+15
AB = 8x+10
Hence the length of segment AB is 8x+10
