A student correctly evaluated an expression with P = -2 and a = 3 and got 3 as the result. Which of the following expressions could she have been evaluating

B

Step-by-step explanation:

A student correctly evaluated an expression where p = -2 and q = 3 and acquired 3 as the result.

And we want to determine which expression could the student have been evaluating.

Thus, we simply need to check each expression by letting p = -2 and q = 3 and see which one equals 3.

Checking the first one:

The result is not 3. Hence, A is not correct.

The second expression:

Therefore, we can conclude that our answer is B.

We can check the other two regardless.

The third expression:

And the fourth:

Thus, neither the third expression nor the fourth is also correct.

In conclusion, our answer is B.

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
