An artifical lake is in the shape of a rectangle and has an area of 9/20 square miles. the width of the lake is 1/5 of the lake. what are the dimensions of the lake?

The length of the lake would be 9/4

Step-by-step explanation:

In order to find the length of the lake, we need to divide the area by the width.

9/20 ÷ 1/5 = 9/4

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
