![40+105+x=180\\ x=35](https://tex.z-dn.net/?f=40%2B105%2Bx%3D180%5C%5C%0Ax%3D35)

The sum of two sides must be greater than the third side.
It can't be 5 because
![5+5=10\not>12](https://tex.z-dn.net/?f=5%2B5%3D10%5Cnot%3E12)
.
It can't be 7 because
![5+7=12\not>12](https://tex.z-dn.net/?f=5%2B7%3D12%5Cnot%3E12)
.
It can't be 17 because
![5+12=17\not>17](https://tex.z-dn.net/?f=5%2B12%3D17%5Cnot%3E17)
.
So it's 12.

Answer:
Step-by-step explanation:
This is not a linear relationship, it doesn't have a set increase or uniform slope and it seems more like an exponential or quadratic curve to me when I graph it. As you can see you cant draw a straight line through the data points so it cannot be a linear relationship.
The answer is 19 pls mark brainliest if correct
Answer:
a. ![y=\frac{2x}{x-5}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2x%7D%7Bx-5%7D)
b. ![y=\frac{2-4x}{x-3}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2-4x%7D%7Bx-3%7D)
Step-by-step explanation:
change switch x and y and then solve for y.
a. ![x=\frac{5y}{y-2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5y%7D%7By-2%7D)
![x(y-2)=5y](https://tex.z-dn.net/?f=x%28y-2%29%3D5y)
![xy-2x=5y](https://tex.z-dn.net/?f=xy-2x%3D5y)
![xy-5y=2x](https://tex.z-dn.net/?f=xy-5y%3D2x)
![y(x-5)=2x](https://tex.z-dn.net/?f=y%28x-5%29%3D2x)
![y=\frac{2x}{x-5}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2x%7D%7Bx-5%7D)
same for b.
b. ![x=\frac{3y+2}{y+4}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3y%2B2%7D%7By%2B4%7D)
![x(y+4)=3y+2](https://tex.z-dn.net/?f=x%28y%2B4%29%3D3y%2B2)
![xy+4x=3y+2](https://tex.z-dn.net/?f=xy%2B4x%3D3y%2B2)
![xy-3y=2-4x](https://tex.z-dn.net/?f=xy-3y%3D2-4x)
![y(x-3)=2-4x](https://tex.z-dn.net/?f=y%28x-3%29%3D2-4x)
![y=\frac{2-4x}{x-3}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2-4x%7D%7Bx-3%7D)
