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
Answer: y = (xm)/3 + b
Step-by-step explanation:
1. Multiply m on both sides
x × m = 3(y - b)
2. Divide by 3 on both sides
(xm)/3 = y - b
3. Add b on both sides
y = (xm)/3 + b
