Answer:

16m - 135

Step-by-step explanation:

Distribute the -5 on -5(m+9) to make -5m-45

Do the same with 6(3m-15) to get 18m - 90

Then arrange the like terms together

-5m + 3m + 18m - 45 - 90

Add the ones with variables

-5m + 3m + 18m = 16m

Then the regular ones

(-45) + (-90) = -135

And finally,

16m -135
