Which polynomial does the model represent?
–x³ + 2x² – 3x + 2
x² + x – 2
–x² – x + 2*****
–x² + x – 2
Can someone please help me

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.

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
