To complete the square, take half of the coefficient of x, 22, square it, then add it to both sides of the equation.
![x^2 + 22x = 9](https://tex.z-dn.net/?f=x%5E2%20%2B%2022x%20%3D%209)
22 / 2 = 11
![11^2](https://tex.z-dn.net/?f=11%5E2)
= 121
![x^2 + 22x + 121 = 9 + 121](https://tex.z-dn.net/?f=x%5E2%20%2B%2022x%20%2B%20121%20%3D%209%20%2B%20121)
![x^2 + 22x + 121 = 130](https://tex.z-dn.net/?f=x%5E2%20%2B%2022x%20%2B%20121%20%3D%20130)
Then you can go from there.
Answer:
rhombus; Measure of angle B = 70 degrees
Step-by-step explanation:
The shape is a rhombus. Angle B and angle A are supplementary, so they add up to 180 degrees.
110 + B = 180
B = 180 - 110
B = 70
It is a rhombus because all sides are equal.

OMGGG I NEED THIS QUESTIONNN TOOOOOOWANNA WORK ON IT
A. y = (2x)^2
Replace x and y with your point
16= (2•2)^2
16= (4)^2
16= 16
1) 2x+1x= 63
2) 3x= 63
3) 3x/3= 63/3
4) x= 21
5) 2(21)+1(21)=63
6) 42+21= 63
The 2 groups would be 42 to 21.
