For the problem, use the discriminant to determine the number of real solutions for the
equation. Then, find the solutions and check to see if they make sense in the context of the
problem.
The length and width of a rectangular patio are, (x + 7) feet and (x + 9) feet, respectively. If
the area of the patio is 140 square feet, what are the dimensions of the patio? Enter the
dimensions to two decimal places.
The equation has (select)real solution(s).
I feet
The width (shorter dimension) of the patio
The length (longer dimension) of the patio is
feet.
