You can put this solution on YOUR website! the length of a floor is 7 feet longer than the width. If x represents the width of the living room, what equation represents the area, y, of the floor in square feet?
Let x = width
then
x+7 = length
.
area is width*length
x(x+7)
x^2 + 7x
.
y = x^2 + 7x (this is what they want)
