Answer 4

I am pretty sure on some of them. I want to double check.

Answer 5

You dont have to answer the short answers just tell me how to work the questions out

Answer 6

Flvs.net? Your teacher isn't Ms. Huercamp is it?

Answer 7

Yes and No

Answer 8

Answer 9

I have Goeb

Answer 10

Omg I remember her!! You should tell her Liam Lohrenz said hi :p I was a pain in the a$$ :DD but you should ask her in a live lesson cause when it comes time for the DBA you're going to have some trouble

Answer 11

I know its my first time asking lol I do my own work

Answer 12

I just am stuck on three of the multiple choices I dont know what im doing wrong

Answer 13

Which three and what did you get on them?

Answer 14

Answer 16

I haven't seen this stuff in forever o.o I'm in Geometry B right now... and this stuff is all gibberish.

Answer 17

lol ya I know the formulas but I keep getting an answer thats not there :/ and I want to keep up my grade soo
