Answer:
Step-by-step explanation:
So first we need to find the area of the trash can so here is the math:
The formula:
A=LxW
Replace the letters with numbers:
8=2x4
So the area is 8 feet now we can create an equation to solve how much money it would take to make the trash can:
8x0.79=$6.32
It would take $6.32 to make the trash can
When two variables have an inverse relationship, the slope is negatively correlated.
This is how I did it:
![5(x + 6) + 11 = 25 - 3x](https://tex.z-dn.net/?f=5%28x%20%2B%206%29%20%2B%2011%20%3D%2025%20-%203x)
use distribution
![5x + 30 + 11 = 25 - 3x](https://tex.z-dn.net/?f=5x%20%2B%2030%20%2B%2011%20%3D%2025%20-%203x)
use addition
![5x + 41 = 25 - 3x](https://tex.z-dn.net/?f=5x%20%2B%2041%20%3D%2025%20-%203x)
use addition and subtraction
![8x = -16](https://tex.z-dn.net/?f=8x%20%3D%20-16)
use division
![x = -16/8](https://tex.z-dn.net/?f=x%20%3D%20-16%2F8)
![x = -2](https://tex.z-dn.net/?f=x%20%3D%20-2)
So your answer is
2x² = 7x + 6
Subtract both terms so that we can get 0 on one side.
2x² - 7x - 6 = 0
Find what factors of - 12 (2 * - 6) add up to be - 7. It's - 4 and - 3.
2x² - 4x - 3x - 6 = 0
2x(x - 2) - 3(x - 2) = 0
(x - 2)(2x - 3) = 0
Now set each equal to 0.
x - 2 = 0
x = 2
2x - 3 = 0
2x = 3
x = 3/2
x = 3/2, 2
