This is the concept of algebra, given that the area of a rectangular pool is (15x-9), the possible dimensions of the pool by factoring will be:
Area=length×width
Area=(15x-9)
factoring the above we get:
Area=3(5x-3)
therefore the possible dimension will be:
length=5x units
width=3 units
Please excuse my dear aunt sally or pemdas
5X-20=4X+7
5X-4x=20+7
X=27°
The standard form would be 602,547
