Answer:
Unit of slipperiness =
![\displaystyle\frac{\text{Peels}}{\text{m}^2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7B%5Ctext%7BPeels%7D%7D%7B%5Ctext%7Bm%7D%5E2%7D)
Step-by-step explanation:
We are given the following information in the question:
The slipperiness of a floor is defined with the help of function:
![S = \displaystyle\frac{P}{A}](https://tex.z-dn.net/?f=S%20%3D%20%5Cdisplaystyle%5Cfrac%7BP%7D%7BA%7D)
where S is the slipperiness of the floors, P is the number of banana peels on the floor and A is the area of the floor.
Now, area of floor has units of meter squared that is,
![\text{m}^2](https://tex.z-dn.net/?f=%5Ctext%7Bm%7D%5E2)
We have to find the appropriate measurement unit for slipperiness of a floor.
This can be done as:
![S = \displaystyle\frac{P}{A}\\\\S = \frac{\text{Peels}}{\text{m}^2}](https://tex.z-dn.net/?f=S%20%3D%20%5Cdisplaystyle%5Cfrac%7BP%7D%7BA%7D%5C%5C%5C%5CS%20%3D%20%5Cfrac%7B%5Ctext%7BPeels%7D%7D%7B%5Ctext%7Bm%7D%5E2%7D)
Thus, slipperiness have a unit of peels per meter squared that is,
![\displaystyle\frac{\text{Peels}}{\text{m}^2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7B%5Ctext%7BPeels%7D%7D%7B%5Ctext%7Bm%7D%5E2%7D)
Let x be 1, y=-12
let x be 2, y=-36
let x be 0, y=-4
let x be 3, y =-108
let x be -1, y=-4/3
let x be -2,y=-4/9
Answer:
9x² + 12
Step-by-step explanation:
Area = Length × Width
Area = 3 × (3x² + 4)
Area = 9x² + 12
X+56<533
-56 -56
x<477 thats the answer
$45 per month x 12 months = 45 x 12 = $540
Monthly payment: $168 x 12 = $2016
Total paid: 2016 + 540 = $2556
Subtract from the total he owes:
4100 - 2556 = $1544
The answer is C.
