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
y = x + 3
as x increases by 1, y increases by 1 (Slope)
when x equals 0, y equals 3 (y-intercept)
He would make $117 because 7x15=105 and 1.50x8=$12.00 add that together you get 117
Answer:
35
Step-by-step explanation:
6(3)=18
18+20=38
38-3=35
Answer:

Step-by-step explanation:
First, we have to write 8 + x, but since it's half of that we write it as a fraction with a 2 on the bottom to halve it.
