Answer:
C. 15
Step-by-step explanation:
1. First, let's solve the system of equations; 
Solve -m - n = 5 for m.
Substitute -n - 5 for m in m - n = -3.
Substitute -1 for n in m = -n - 5.
2. Okay, now that we know m = -4 and n = -1, let's solve for m^2 -n^2.
Therefore, the answer is C. 15!
Let the four numbers be A,B,C,D in ascending order.
The key is in conditions 2 & 3.
B-C=-4, and B+C=0
therefore B=-2, C=2 by solving the two previous equations.
Given that the product of the two greatest numbers is 6, we have C*D=6, or
D=6/C=6/2=3
Now since the sum of all the four numbers is -6, we have
A+B+C+D=-6
A-2+2+3=-6
A=-6+2-2-3=-9
Check: we were told smallest divided by greatest = A/D=-9/3=-3 ok.
So the numbers are
A=-9, B=-2, C=2, D=3.
