I'm not sure if A B C D are answers, but I can say for sure that C is positive and A, B, and D are negative.
A:
[tex]-7*13[/tex]
Since there is only one -1, the expression is negative;
[tex]-7*13=91 [/tex]
B:
[tex]14*-2[/tex]
Here as well, there is only one -1, so the expression is negative;
[tex]14*-2=-28[/tex]
C:
[tex] \frac{-14}{-7} [/tex]
The -1 cancels out;
[tex] \frac{14}{7} =2[/tex]
D:
[tex] \frac{-42}{6} [/tex]
Here, you can't cancel the -1 out, so it remains negative;
[tex] \frac{-42}{6} =8[/tex]
Sorry for the delay, hope this helps :)
