Answer: The answer is 20
Step-by-step explanation: If all interior angles are 162o , polygon has 20 sides.
X = -5
The goal of this problem is to solve for x.
To solve x in this problem you need to find a way to get it by itself on the left side, the way to do this is divide -5x by -5.
You then also have to do the same for the right side. This gives you -5.
Answer:
1.5

The slope is 1.5. If you look at 3 and 4, you can see it increases by 1.5.
Answer:
4(x - 
)² = 0
Step-by-step explanation:
Given
4x² - 4x + 1 = 0
To complete the square the coefficient of the x² term must be 1
Factor out 4 from 4x² - 4x
= 4(x² - x) + 1 = 0
add/subtract ( half the coefficient of the x- term )² to x² - x
4(x² + 2(- )x + 
- ) + 1 = 0
4(x - )² - 1 + 1 = 0
4(x - )² = 0
