HOPE THIS HELPS THESE ARE ALL CORRECT!!!!
looks like the questions might be randomized... just our luck
I got a 65.2% with love cats answers.
It wasn't the 100% I was looking for but it's better then what I would have scored guessing.
The
i recommend trying to get the answers by typing the problems into mathway
can you guys post the written out answers once u finish.its easier then putting just the number
nope angle is wrong. guys they switch up the test for everyone. non of us will have the same answers
bruh the answers are slightly different for me

All of these should be correct i took the test and these were the correct answers.
so why didnt u give us the actual answers????????? i guess ill do it myself then. lemme go finish the test.
I found out that some of the questions are the same. Just use all the written answers from imheretohelp anonymous and Angel and match them to your question. I'll write out what I got in a bit.
Great job! It's always a good idea to cross-check your answers with others.
If you use @imheretohelp, @Anonymous, and @Angel's answers and match them to your questions, you should get an A. Like, most of my test matched with Angel's answers, and the ones that didn't I found on imheretohelp and Anonymous' answer keys. The only problems I had to do on my own were 14, 16, and 21. So yeah, just use a little bit of everybody's and you'll get an A. You might not get 100% because there are a couple you have to do on your own, but you definitely won't fail.
I got a 7/23 with need help?’s answers
i got a 13/23 56.52 with @algebra
Eh, nice try tho :)
here are asnwers i didnt find on any of the above peoples tests (im not gunna be like them and put the whole test including a bunch of repeat answers,this way its easier for you to find them, if you have a similair situation please type it this way for ppl later on so they dont have to look thru so many)
12. A: 6w^6 + 2w^8
21. A: about 3.11 hours
23. D: x = -8
this also has more answers for part 1 if you still needed some for that but its mainly for Rational Expressions and Functions Unit Test Part 2
since you cant post URLS you have to add questions.llc right before the link below

I Need help with the Conexus test in Washington state connections academy
I also had to do number 23 on my own, but you can just substitute the multiple choice options into the equation using a scientific calculator. If you have one that's not on a phone or computer like I do, it'll say something like Divide By Zero ERROR for one of the answers. That's the right one.
idk if its just me but i have 16 questions :_)
no, but we can help you learn to solve some problems if you post them.
