#'s 18 and 21, are the ones I'm having trouble with.

OpenStudy (anonymous):

18 is currently written in set notation. x has to be lesser than or equal to 3 or x has to be greater than 5 and lesser than or equal to 11. I'm not completely sure about 21. :(

OpenStudy (anonymous):

Hmm... well thanks for the help anyhow!
