help pleaseee

Answer 1

for the area of a rectangle, you can use the following equation:
A=lw

Answer 2

so basically, you just divide the given area with the given width to get the length.

Answer 3

factorize and simplify 36x^4 -64x^2 first, you should get 4x^2(9x^2 -16).

Answer 4

what do i do after that

Answer 5

then 6x^2 -8x= 2x(3x-4)

Answer 6

then divide 4x^2(9x^2 -16) by 2x(3x-4)

Answer 7

eliminate 2x

Answer 8

then :\[2x(3x-4)(3x+4) /(3x-4)\]

Answer 9

eliminate (3x-4)
you should end up with 2x(3x+4)

Answer 10

and that's your width.

Answer 11

if you like you can expand it into 6x^2 +8x

Answer 12

thank you:)
