You can put this solution on YOUR website! A large rectangular movie screen in an IMAX theater has an area of 7,719 square feet. Find the dimensions of the screen if it is 10 feet longer than it is wide.
width = x
length = x+10
Equation:
x(x+10) = 7719 sq. ft.
------
x^2 + 10x - 7719 = 0
x = 83
x+10 = 93
