The length of a rectangle is 3 ft more than twice the width, and the area of the rectangle is 77ft. find the dimensions of the rectangle.

Let x = width
2x + 3 = length

Area of rectangle is length times width

x(2x + 3) = 77
2x² + 3x = 77
2x² + 3x - 77 = 0
2x² + 14x - 11x - 77 = 0
2x(x + 7) - 11(x + 7) = 0

(2x - 11)(x + 7) = 0

x = 11/2, - 7

Distance/measurements can't be negative so x = 11/2

The length:
2(11/2) + 3
11 + 3
14

Your width is 11/2 feet and your length is 14 feet. 

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
