Answer:
The answer to your question is the last option (x + 6)² = 13
Step-by-step explanation:
Data
x² + 12x + 23 = 0
Process
1.- Subtract 23 in both sides
x² + 12x + 23 - 23 = -23
2.- Simplify
x² + 12x + ( ) = - 23
3.- Complete the perfect square trinomial
x² + 12x + (6)² = -23 + (6)²
4.- Factor
(x + 6)² = -23 + (6)²
5.- Simplify
(x + 6)² = -23 + 36
6.- Result
(x + 6)² = 13
Answer: The slope of a vertical line. A vertical line has undefined slope because all points on the line have the same x-coordinate. As a result the formula used for slope has a denominator of 0, which makes the slope undefined.
A horizontal line has slope 0 because all its points have the same y-coordinate. As a result, the formula used for slope evaluates to 0.

Answer:
C
Step-by-step explanation:
To solve, use inverse operations:
Now we solve for both +/- 7.
x+6=7
x=1
x+6=-7
x=-13
