If l is the midpoint of km find the lengths of kl, lm, and km

A midpoint is half way, so it divides the segment KM into two equal halves. In this problem segment KL will be equal to segment LM.

2x+1=3x-4
Subtract 2x from both sides
1=x-4
Add 4 to both sides
5=x

KL (2x+1)
Substitute the answer for x in expression
=2(5)+1
=10+1
=11

LM (3x-4)
=3(5)-4
=15-4
=11

KM
=KL+LM
=11+11
=22

The answer is D) 11, 11, 22

Hope this helps! :)

Your answer should be 1/3. i hope i could ! good luck : )
