Answer:
X=36
Step-by-step explanation:
3x+72=180
3x=180-72
3x=108
x=36
Answer:
The answer is A undefined
Step-by-step explanation:
The slope is given by
![m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
![m=\frac{9-(-13)}{17-17}=\frac{22}{0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B9-%28-13%29%7D%7B17-17%7D%3D%5Cfrac%7B22%7D%7B0%7D)
which is undefined (division by zero)
5x’2-4x+7-4x-2
We add the two 4
5x’2-8x+7-2
5x’2-8x+5
The answer is
5x’2 -8x +5
