Answer:
C
Step-by-step explanation:
-7 is less than |-6| because the absolute value of |-6| = 6
|9| = 9, which means 6 is less than 9.
|-13| = 13. This implies that 9 is less than 13.
Therefore, from least to greatest, we have:
-7, |-6|, |9|, |-13|

Answer:
B. x = -6, x = 4
Step-by-step explanation:
The constant on the left wants to be 1, the square of half the x-coefficient. We can get it to be that value by adding 8 to the equation.
x² +2x +1 = 25
(x +1)² = 25 . . . . . . . rewrite the left side as a square
x +1 = ±√25 = ±5 . . . . take the square root
x = -1 ±5 . . . . . . . . . subtract 1
x = -6 or x = 4
