2,7 are incorrect
6th also seems incorrect

others are correct

ria23 · Answer

I guessed on 2. ;n;
7, I wasn't sure if it was a or b, and since a is wrong, would b be the right answer?
Same for 6, I was torn between a and c, so I went with c...

anonymous · Answer

For 6th, according to factor theorem it should be A

ria23 · Answer

I thought so. c: But c looked right to me too... 
Any ideas on 2 or 7?

anonymous · Answer

For 7 its B and for 2nd.... it will take time :(

ria23 · Answer

Awesome! And that's alright. c: If yhu wanna help and take the time that'd be awesome. I can wait, if not, that's ok too. I'll still medal yhu for helping. ^.^

If yhu do number 2 tho, could I ask yhu to do it with me so I can kind of understand how to do it so when i do my test later on I don't get stuck on a similar problem?
