Answer:
Step-by-step explanation:
hello :
x²+6x+9 = 20
(x+3)²-20 = 0
(x+3)²-√20 = 0
(x+3-√20)(x+3+√20)=0
x+3-√20=0 or x+3+√20=0
x = -3+√20 or x = -3-√20 answer B

Answers:
Angle a: 148 degrees
Angle b: 32 degrees
Here’s a picture of my calculations:
Answer:
A' (8,-7)
B' (8,-7)
When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative
