Let the width be w, then length = 2w - 1
Area = length times width = w(2w - 1) = 21.
Thus, 2w^2 - w = 21 or 2w^2 - w - 21 = 0
Solving the quadratic equation gives that w = 3.5.
Therefore, width is 3.5 ft and length is 2(3.5) - 1 = 6 ft.
x = 3.
Plug in 3 for x in the equation
14(3) + 64
Remember to follow PEMDAS. First, multiply 3 with 14
3 x 14 = 42
Finally, add 64
42 + 64 = 106
106 is your answer
