Since you know the value of n, you can substitute/plug it into the equation:

-4n² + 11          Plug in 3 into "n" since n = 3

-4(3)² + 11       Find 3² -->    3 x 3 = 9

-4(9) + 11       Multiply -4 and 9

-36 + 11

-25

Answer:

B) A/l

Step-by-step explanation:

Isolate the variable, w. Note the equal sign, what you do to one side, you do to the other.

Divide l from both sides of the equation:

A = l * w

(A)/l = (l)/l * w

w = A/l

B) A/l is your answer.
