Answer:

6m + 5

Step-by-step explanation:

This is the answer because:

1) First, find all the like terms

Like terms: 17m, -9m, -2m

Like terms: -2, +7

2) First, do 17m - 9m which is 8m

2) Then do 8m - 2m which is 6m

3) Finally, do -2 + 7 which is 5

Therefore, the answer is  6m + 5

Hope this helps! :D
