35. 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!

49. You know, if your answers aren't here, let me give you a tipof getting ALL answers on brainly.
If you go to a link in Brainly (which you don't have to, I'm just telling you) you will see a little black lock in the upper left corner of your screen. Click on it, and you will get all sorts of crazy info, but there will be something like "Cookies: so and so number in use."
I took Intro to ComApps lately, so cookies aren't snacks you eat while having a movie. It is actually like your ID card to an entrance. So, now that you went to the site. When you go back, Brainly will recognize you, even though there are trillions of users on that site. How do they recognize you came back a second time? Chocolate-chips cookies!!!

ANYWAY, BACK TO THE POINT!!! IF THERE IS NO ID CARD< HOW WILL THEY EVER RECOGNIZE YOU?!

Go into Setting in Chrome, I have one, if you use something else, go to settings there, or whatever. Next, go to Cookies and Other Site Data, scroll to the bottom, and there will be a pod saying Sites with blocked Cookies, or something like that. Add Brainly . com in, and now you are like a super spy gathering all your information, without those horrid no-answers-for-you monsters called Brainly. So there! Hope it helps!

50. There may be some spelling errors, *tip of. Well, this worked for me. I am about to do the same right now, I'm literally stuck in my test, anyway, there's also Quizlet, if that helps. I do not find Chegg all that helpful, signing in and all, Course Hero never gives you full docs, so I guess we'll have to search each question individually on Brainly. Still, something is better than nothing...

51. Just use mathway.com for your questions, some questions you might have to connect and do quick little math but its nothing hard and plus teachers say we can use calculators. Its really a free A with mathway. good luck future people on the test.

56. All questions on part 1 are solvable by Mathway. You can use Mathway to easily find the answers to these just make sure you put in the kind of answer you want. There is no way to help here since the questions change every test. Make sure you get 1 or 2 wrong so you dont seem too sus.
