Rectangular swimming pool has a perimeter of (6x-6) feet and a width of x. find the length

5x-6

4x-6

2x-6

2x-3

The first thing you should know for this case is that the perimeter of a rectangle is defined as:

P = 2L + 2W

Where

L = length

W = Wide

We then have to clear the length:

L = (P-2W) / 2

Substituting the values

L = ((6x-6) - 2x) / 2

Rewriting:

L = ((3x-3) - x)

L = 2x-3

Answer:

the length is

2x-3
