This is a difference of squares. Every time you have the difference between two squares, you can factor it as the product between the sum and the difference of the roots:
In your case, the squares are
So, the difference between the squares, 
can be written as the multiplication between the sum and difference of the roots:

Answer:
4) Alternate angles
Step-by-step explanation:
Alternate angles are on the opposite corners of the line of the angle, and 10 and 14 are on opposite corners, so that makes them alternate angles. I hope this helped you!
40 + 2x - 30 + x + 20 = 180
3x + 30 = 180
3x = 150
x = 50
m<B = 2x - 30
m<B = 2(50) - 30
m<B = 100 - 30
m<B = 70
