A rectangular parking lot has a length 20 H more

Mathematics

Let the width = X

The length would be X + 20

Area = Length x width:

2400 = x * (x+20)

Simplify:

2400 = x^2 + 20x

Subtract 2400 from both sides:

x^2 + 20x - 2400 = 0

Factor:

(x-40) (x+60) = 0

Solve for both x's:

x = 40 and x = -60

The dimensions of a parking lot have to be positive values so you would use x = 40.

The width = x = 40

The length = x +20 = 40+20 = 60

The dimension of the parking lot is 40H x 60H

Answer:

The height is 0 when it "drops".

3/2x + 9 = 0

3/2x = -9

3 = -9(2x)

3 = -18x

3/-18x

Change signs, time cant be negative.

x= 6

Another interpretation; Slope is negative it is falling. This interpretation is more accurate.

-3/2x + 9 = 0

-3/2x = -9

-3 = -9(2x)

-3 = -18x

6 = x
