x = -12x = 6
x = -12 - 11. Multiple ChoiceWhat is the reason that absolute value is always written as a positive?Absolute value is talking about numbers so it must be positive.Absolute value does not always have to be positive.Absolute value is like a clock it has only positive numbers.Absolute value is talking about distance, distance is always measured by positive numbers.
- 12. Multiple ChoiceWhat is the absolute value of -12?012-12It's hard to say
