a rectangular swimming pool is represented by x as the width and one less than twice the width as the length. if the area of the swimming pool is given by 28 sq. ft., which equation could be used to model the area of the swimming pool?

a) 28 = 2x - 1•x

b) 28x = 2x - 1

c) 28 = (2x - 1) + (x)

d) 28 = (2x - 1)(x)

28=(2x-1)(x)

Step-by-step explanation:

The swimming pool is rectangular in shape.

Hence the area of it is given by:

l * w

where l = length of the rectangular swimming pool

          w = width of the rectangular swimming pool

In this question it is given:

width = w = x

length = l = 2x - 1

Area = 28 sq.ft

Hence:

Area = l * w = (2x-1)(x)

28 = (2x-1)(x)

this is a very good question

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
