Question

Evaluate the expression when c= -7

Answer 1

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.

$(-7)^{2} + 4(-7) -5$

Now simplify:

49 - 28 - 5

16

When c = -7, the expression evaluates to 16.
