I am about to submit so i am not positive about ALL of these. but most of them i am sure of.

Let me clear up this confusion for you all.

Yes, Connexus switches up tests for Algebra every now and then, so you can't just give the letter answers to each question, because we have no way of telling which is correct or not.

Anyway, I hoped this help you guys. Don't trust any of those answers. Not because they're wrong, but because you can't know if they're right. You'll either have to do the test yourself and look up each individual question.

Well sorry for any confusion. I took the test and then wrote down all the answers that had (1 pt) next to them, because those are the correct answers. Maybe the test switches the order around for different students? I don't know. Good luck to you all and I apologize for the confusion!!

Lol it's funny watching people do this and getting all the wrong answers. Even though I'm about to fail myself it's fun to watch anyway.

This is for everyone attending Connections Academy in Utah that is on Unit 6, Lesson 7: Polynomials and Properties of Exponents Unit Test

I got all the answers right (21/21) thanks to the "polynomial calculator" so if you don't trust my answers... search polynomial calculator and do your own work.

1. C -x^2-x+2
2. A -x^2+3x+15
3. B -2x^2-2x+5
4. A 5,2
5. B m^2+2
6. A 6x^3+7x^2-x-5
7. A 15t-4
8. D f^6
9. B 144^12
10. C x^11
11. A 4^3*4^5<4^12
12. A 2^4*2^4>2^7
13. B 1
14. B 1/16
15. B 1.61*10^8
16. C 3.3*10^-7
17. C 36t^6
18. D -5x^2+4x
19. A -12k^4-16k^3+20k^2
20. D 2k^2-7k-4
21. C -2y^2+9y-4

Short Answers: (Not Sure if Correct Yet)
22. Blue Triangle: 4x+2+7x+7+5x-4 = 16x+5
Pink Triangle: x+3+2x-5+x+7 = 4x+5

Blue-Pink = (16x+5)-(4x+5)

4*3+2+7*3+7+5*3-4 = 53
3+3+2*3-5+3+7 = 17

23. Eden completed the problem correctly.
Emma was wrong by multiplying 6*6.
Erin was wrong by multiplying 2*5.

24. 3.54*10^7=3x10^8t
t = 3.54/3 * 10^-1
t = 3.54/30 = o.118 seconds

I tried to double check all my answers. I hope I typed all of the correctly. Good luck! You're welcome :D

They probably randomized the tests up

Could anyone be kind enough to write the actual answer next to their letter choice? It would clear a great deal of confusion.

No way that's right ^

Kelsey is wrong.

For all the kids out there who are using this to cheat on all your assignments please listen... 2020 was my first year being homeschooled, and at first I was doing pretty good, but then, like a month or so into it I found jiskha and started to cheat on everything, and wasn’t learning at all, it is now the end of my school year and I am completely screwed! I cheated all year and I regret it soooo much! It was one of the WORST decisions I have ever made, I can’t go back and relearn what was taught this year and now I have to go into my first year of (in person) high school and have absolutely no clue what to do, it will now be so much harder for me to learn anything, and it will be embarrassing because i don’t even know half the stuff the other students do. Keep in mind that I’ve never been good at school and have always been at the bottom of the class, but now I’ve just made it a million times worst. Although cheating was the “easiest” way and seemed to be great idea because the work was being done, I got a good grade, and didn’t even have to do the work, which sounds like a dream, I know, but when I realize that I just made my life a hell of a lot harder then it would be if I just did the work myself, and put in that extra work, it was to late, I can’t turn back, and now I have to suffer the consequences, so please!! I know it’s hard right now, and you don’t want to do the work, but if you cheat it will only make your life harder in the end. Don’t make the same mistakes I did, and trust me when I say, cheating is NOT worth it!! Take it from someone who knows first hand at what it’s like, I’m not trying to tell you what to do, because it’s your life, just PLEASE think about it!!! YOU CAN DO THIS, I BELIVE IN YOU!! Good luck to everyone, I hope it all turns out good for all of you ♥️
