Answer 5

assume a represents a positive number
|x|>a implies that x>a or x<-a
example: |x|>5 this represents numbers greater than 5 or also less than 5 you know since |-8|=8>5

these numbers I have shaded are numbers that have a distance that is greater than 5 from 0
so what do you think the answer is for |x|>11?
