Area=500 height=2x+6 width=4x-3: what is the exact width?
1 answer:
Area of a rectangle is lxb
(4x-3) * (2x+6) = 500
{(4x * 2x) + (4x * 6)} + {( -3 * 2x) + (-3 * 6)} - multiplying the factors
{8x^2 + 24x} + {-6x + -18}
8x^2 + 24x -6x -18 - removing the brackets
8x^2 +15x -18

Answer: They washed 60 small cars.
Step-by-step explanation:
5x + 10y = 800
y = 50
5x + 10(50)
5x + 500 = 800
Subtract 500 from each side
5x = 300
Divide each side by 5
x = 60
Answer:
The equation would be y=3x-3 so that makes the slope -3
