Step-by-step explanation:
Given
x² - 9x + 4 = 0 ( subtract 4 from both sides )
x² - 9x = - 4
Using the method of completing the square
Add ( half the coefficient of the x- term )² to both sides
x² +2 (- 
)x + 
= - 4 +
(x - )² = 
Take the square root of both sides
x - = ± 
= ± 
Add to both sides
x = ± ← exact solutions
Aloha!
This is a very simple question.
All you would have to do is divide!
It would be 56.3 or rounded it would be 56!
Adios! :)

Look at image I attached below.
Step-by-step explanation:
Important points to memorize when finding missing angles like these:
- Two angles directly <u>across</u> from each other, <u>not next to</u>, are equal.
- <u>All</u> angles that are on one side of a straight line add up to 180°, because a straight line has an angle measure of 180°.
- A full spin-around equals 360°.
- <u>All</u> angles in <u>any triangle</u> add up to 180°.
When you know all these important rules, the rest is just a matter of adding and subtracting.
Y=2x-5 because parallel means keep the slope the same and the formula is y=mx+b b is y and y is -5 so your answer is y=2x-5
The area of a square with side s is
Area = s²
Here
Area = 8² = 64 sq cm
Answer: 64
