Answer:
x = ± 7
|-7|-2=5
|7|-2=5
± means positive or negative
Step-by-step explanation:
|x|-2=5
Get x by itself by adding 2 to both sides.
x - 2 + 2= 5 + 2
-2 + 2 cancels out
x = 5 + 2
x = 7
Absolute value is how far a number is from 0.
x can be either positive or negative.
Answer:
A
Step-by-step explanation:
observe
x² + 12x + y² + 10y = –45
add 36 + 25 on both side
x² + 12x + 36 + y² + 10y + 25 = –45 + 36 + 25 = 16
(x + 6)² + (y + 5)² = 16
6 equals 6*10^0 which os 6*1=6
