Answer 2

@Cweezie23

{x | x < -5} ∩ {x | x > 5}

This is the intersection of two sets.

All numbers less than -5 and all numbers greater than 5.

Answer 3

@Cweezie23

Please name a number that is less than -5 and greater than 5 at the same time, okay?

Answer 4

@jigglypuff314

Your answer here is incorrect. It appears that you formed the union of the two sets rather than the intersection. Do check your answer.
