Answer 2

(D)
`15m+2n`

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.
