Answer:
your answer should be x = -3
Let the width be x
Length= x+7
Area=lw
99=(x+7)(x)
99=x²+7x
0=x²+7x-99
x= -14.04 or x=7.04
Since a length cannot be negative, the width is 7.04 ft and the length (7.04+7)=14.07 ft
Hope I helped :)
(5x+1)(5x-1) tell me if you want to know how to do this problem :)
I think it would just be DB? Because it’s the same line, but I might be wrong.
