Answer:

(D) 15m+2n

Step-by-step explanation:

The  equation is given by:

8m+4n+7m-2n

Let y= 15m+2n, then

Rewriting the like terms together and then adding or subtracting them, we have

y=8m+7m+4n-2n

y=15m+2n

Hence, simplified form of the given equation is 15m+2n.

Therefore, option D is correct.
