A rectangle has a length of 18 meters less than 8 times its width. If the area of the rectangle is 4176 square meters, find the length of the rectangle.

28

step-by-step explanation:

because that's the answer

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

the answer is  

c.

90.0π cm^2

hope you got it.
