a rectangular flower bed is enlarged so that its area increases by 24 ft^2. the enlarged flower bed is a rectangle and its area is x^2+11x+24 ft^2. what expressions represent the dimensions of the flower bed before the increase? enter your answers in the boxes.

The expression before the flower bed was increased is the x. to solve how much it was increased, you must factor the given quadratic equation:

x^2 + 11x + 24 = 24
( x + 3 ) ( x + 8 ) = 24
( x + 3 ) ( x + 5 + 3) = 24
the sides of the rectangular flower bead was increase by 2 ft each
