Answer:I will not do it all. I will set it up for you.
Area = length times width
A = LW
(9x^2 + 6x - 3) = L(3x - 1)
To find L, divide both sides by (3x - 1) using long division.
After finding L, go back to A = LW but this time use the NEW AREA given to be (9x^2+ 12x+ 3).
Set Up:
(9x^2+ 12x+ 3) = LW
Step-by-step explanation:Note: Plug the L you found above into (9x^2+ 12x+ 3) = LW and then solve for W.
no hate this is the best answer i could find
