Problema Solution
The Jones's pool has a length that is 10 feet less than twice the width. Express the area in a simplified form.
Answer provided by our tutors
we will assume the pool is rectangular
l = the length of the pool
w = the width of the pool
A = l*w the area of the rectangular pool
the Jones's pool has a length that is 10 feet less than twice the width:
l = 2w - 10
plug l = 2w - 10 into A = l*w
A = (2w - 10)*w
A = 2w^2 - 10w is the area in simplified form.
