Question

PLEASE HELP!!! The side lengths of a square are each 5q. By adding 3 to the length and subtracting 3 from the width, a rectangle is made. What is the area of the rectangle? a. 10q^2-6 b. 9q^2+25 c. 25q^2-9 d. 25q^2-30q-9

Answer 1

Answer:

Option C

Step-by-step explanation:

When you put the write the scenario in an equation, it'll look like

(5q+3)(5q-3) for the new width times the new length

Factor these, and you shall get 25q^2+15q-15q-9. Simplify that into

25q^2-9
