Question 173648
your equation has a slight glitch


the total area of the flower bed is 9*5 or 45 ft^2
if the border is 24 ft^2, then the portion in your eqn should be 45-24 or 21


(9-2x)(5-2x)=21 __ 4x^2-28x+24=0


dividing by 4 __ x^2-7x+6=0


factoring __ (x-6)(x-1)=0


x equals 1 and 6, but 6 is greater than the width of the bed __ so 1 is the answer
