Answer:
The answer to the expression is 16.
Step-by-step explanation:
So, when c = -7, first plug in -7 to every c variable in the expression.
![(-7)^{2} + 4(-7) -5\\](https://tex.z-dn.net/?f=%28-7%29%5E%7B2%7D%20%2B%204%28-7%29%20-5%5C%5C)
Now simplify:
49 - 28 - 5
16
When c = -7, the expression evaluates to 16.
