Answer:
x=20
Step-by-step explanation:
For A to be parallel to B, the angles of 5x+20 and 3x+60 must be equal.
5x+20=3x+60
2x=40
x=20
The shape is a parallelogram because the length of the sides based on the coordinates
Answer:
x = 55
Step-by-step explanation:
![\frac{x}{5} - 7 = 4 \\ = > \frac{x}{5} = 4 + 7 \\ = > \frac{x}{5} = 11 \\ = > x = 11 \times 5 \\ = > x = 55](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B5%7D%20%20-%207%20%3D%204%20%5C%5C%20%20%3D%20%20%3E%20%5Cfrac%7Bx%7D%7B5%7D%20%20%3D%204%20%2B%207%20%5C%5C%20%20%3D%20%20%3E%20%20%5Cfrac%7Bx%7D%7B5%7D%20%20%3D%2011%20%5C%5C%20%20%3D%20%20%3E%20%20x%20%3D%2011%20%5Ctimes%205%20%5C%5C%20%20%3D%20%20%3E%20x%20%3D%2055)

Using the distribution method:
x^2 + 12x - 8x = 14 + x^2 - 4x
x^2 + 4x = x^2 - 4x + 14
Now, I'm isolating x by moving all the x's onto one side of the equation:
x^2 - x^2 + 4x + 4x = 14
Combine like terms (x^2 cancels out):
8x = 14
x = 14/8
Simplified: x = 7/4
