4a2 (less than or equal to) a + 1 (less than or equal to) 3a + 4
I'm assuming I should put this on a line, like I did with some other problems on my worksheet, right? But I have no idea how I would show 4a2 on a line! I have no idea how to do this.
Thank you so much!

Read my question, and then look at this message for my results! 
Harper,
I think I understand how to do this... here's my work.
4a  2 < a + 1 < 3a + 4
I separated them into two pieces:
4a2 < a + 1 and a + 1 < 3a + 4
Then, I added two to each side of the first one, and took away 1 from each side of the second one.
4a < a + 3 and a < 3a + 3
I took away took away a from each side of the first one and 3a from each side of the second one.
3a < 3 and 2a + 3
Then, I will put it on a line. Does my work look right?

bobpursley,
4a2<a+1
3a<3 or a<1
a+1<3a+4
3<2a
3/2 < a
