Answer:
$38.72
Step-by-step explanation:
this is for 8.75% sales tax which is what I would think it would be as $8.75 extra as tax is ridiculous on something this small
S=d/t so in this case it's 75/12 which is 6.25. Round it and you got 6 miles per hour.
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.
