Answer:
B and F
Step-by-step explanation:
Given
x² + 4x + 4 = 12 ( subtract 4 from both sides )
x² + 4x = 8
Using the method of completing the square to solve for x
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 8 + 4, that is
(x + 2)² = 12 ( take the square root of both sides )
x + 2 = ±
( subtract 2 from both sides )
x = ±
- 2
= ± 2
- 2
Hence
x = 2
- 2 → B
x = - 2
- 2 → F
The GCF is of 11ab +32ab is 43ab
Right answer is C
We can solve it with the formula
y=mx+b
b is the point where graphic starts
Table C shows us 0 by x, and -4 by y
So the graph starts at (0, -4 )
8 - (-10) = 18
18 / 3 = 6
hope this helps
