Ans: A
Note that $m$ and $n$ are the roots of $2x^2 + 5x = 14$. Therefore, we have
Note that $m$ and $n$ are the roots of $2x^2 + 5x = 14$. Therefore, we have
$\begin{array}{rcl}
m + n & = & \dfrac{-5}{2} \\
mn & = & \dfrac{-14}{2} = -7
\end{array}$
Therefore, we have
$\begin{array}{cl}
& (m+2)(n+2) \\
= & mn + 2m + 2n + 4 \\
= & mn + 2(m+n) + 4 \\
= & -7 + 2(\dfrac{-5}{2}) + 4 \\
= & -8
\end{array}$
