Answer:
28
Step-by-step explanation:
If point M is the midpoint of the segment QR, then we would have that the length of both segments QM and MR are the same.
Therefore we know that:
[tex]QM=MR\\16+x=2(x+2)\\16+x=2x+4\\16-4=2x-x\\12=x[/tex]
Substituting this answer in QM:
[tex]QM=16+x\\QM=16+12\\QM=28[/tex]
Therefore, the length of QM is 28.
