Answer:
The answer is B. 3
Step-by-step explanation:
In order to determine the answer, we need to know about evaluating numbers.
In an expression where there are variables, we can replace all of them by values and then we will see the result of the expression. The procedure is called "evaluating numbers".
In this case, we have the next expression:
[tex]-x^2-4x[/tex]
If we replace the "x" variable by -3, we get:
[tex]-(-3)^2-4*(-3)\\-9+12\\3[/tex]
According to the possible options, the answer is the letter B. 3
