Answer:

C. 15

Step-by-step explanation:

1. First, let's solve the system of equations; $-m - n = 5, m - n = -3$

Solve -m - n = 5 for m.

$-m -n = 5$
$-m-n+n=5+n$
$-m = n + 5$
$\frac{-m}{-1} = \frac{n+5}{-1}$
$m = -n - 5$

Substitute -n - 5 for m in m - n = -3.

$m - n = -3$
$-n - 5 - n = -3$
$-2n-5=-3$
$-2n-5+5=-3+5$
$-2n = 2$
$\frac{-2n}{-2} = \frac{2}{-2}$
$n = -1$

Substitute -1 for n in m = -n - 5.

$m = -n - 5$
$m = -(-1) - 5$
$m = 1 - 5$
$m = -4$

2. Okay, now that we know m = -4 and n = -1, let's solve for m^2 -n^2.

$m^2-n^2$
$(-4)^2-(-1)^2$
$16 - (-1)^2$
$16 - 1$
$15$

Therefore, the answer is C. 15!
