here you guys go.. these were the correct answers for me and i got 100% so good luck on that test :)
Be careful of these lists of answers without explanations. Sometimes kids deliberately post wrong answers. Sometimes teachers and/or test publishers mix the questions and answer choices up. Sometimes they change them completely!
Be aware!
bruh this dude names rlly bakugo and y’all trust that wth
Does anyone have the whole test?

DO NOT *i repeat* do NOT use these answers in this order!! i guarantee we do not have the same test. this is just for the homies out there who happen to have the some of the same questions ‼️
idk but he has 9 dislikes so im assuming not but the first 2 questions answers are right.
my first one is "What is the sum or difference?" 3x^8 + 7x^8
but the questions are different for some people
