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.
