20/4.... 5cm is ur answer
f/g (x) = (3x + 2) / (3x - 5)
Domain = {x| x = all real values, x ≠ 5/3}
Answer:
Dimension: 2inches by 4 inches
Step-by-step explanation:
Given
![Width = 2wice\ Length](https://tex.z-dn.net/?f=Width%20%3D%202wice%5C%20Length)
Required
Determine the dimension.
This is calculated as :
![Area = Length * Width](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2A%20Width)
![A = L * W](https://tex.z-dn.net/?f=A%20%3D%20L%20%2A%20W)
So:
![A=L * 2L](https://tex.z-dn.net/?f=A%3DL%20%2A%202L)
![A=2L^2](https://tex.z-dn.net/?f=A%3D2L%5E2)
Substitute 72 for A
![72=2L^2](https://tex.z-dn.net/?f=72%3D2L%5E2)
Divide bith sodes by 2
![36 = L^2](https://tex.z-dn.net/?f=36%20%3D%20L%5E2)
Take square root of both sides
![L = 6](https://tex.z-dn.net/?f=L%20%3D%206)
Recall that:
![Width = 2 * Length](https://tex.z-dn.net/?f=Width%20%3D%202%20%2A%20Length)
Hence:
![LEnhth= 0 * 2](https://tex.z-dn.net/?f=LEnhth%3D%200%20%2A%202)
![LEnhth= 2](https://tex.z-dn.net/?f=LEnhth%3D%20%202)
Hence, the dimension is: 2 by 3 inches
No it is not a function because the x coordinate 0 has 2 y coordinates which is 4 and 5. a function means each x coordinate can only have one y coordinate
