15-4x is the answer have a good day
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
The answer is 10 radical 11
(30 feet) / (60 feet) = (30 / 60) (no unit) = 1/2 .
