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.
