<p>yeah it was 17 times 19 which give you 323</p>

<p>323 is what I got, honestly I didn’t try to find 324 though I just assumed it wouldn’t be right after I got 323</p>

<p>it was 17 * 19 because those are the largest odd numbers you can have that equal 36</p>

<p>How about the one where it asked what is y*z?</p>

<p>i think it was 3 but i dont remember</p>

<p>yeah it was 3</p>

<p>I think I got 3 too, ethan.</p>

<p>Shape question? The last one…</p>

<p>I ended up getting 3 x 1 so yea 3</p>

<p>Anyone want to create a google doc so we can figure out which answers/questions we are missing?</p>

<p>Midpoint was giving you guys trouble? I thought it was easy, while the shape one, the 7/sin56 one, and the 2a + 2b were hard (statistically, I can hope to get one of those guesses right, right?). I guess we were all taught different. They said that lower left point was (m,k), and the top left was 4 points above k, and the lower right was 6 points right of (m,k), therefore the midpoint of the diagonal is (m+3,k+2). Numbers may be different, but the concept is as I described. I felt like there weren’t as many impossible questions overall, but I felt like there were more really tough but solve able problems.</p>

<p>the circle with legnth AO was 7/sin28. 2a+2b<a+b+2c </p>

<p>and what is the shape one to which you refer?</p>

<p>I think it was 7/cos 56 but tbh i dont remember what i put. And the triangle one you had to know that a + b >c</p>

<p>idkhur it was definitely 7/sin28.</p>

<p>Oh…well was there an answer that had cos in some other question cuz i feel like i put cosine for some question</p>

<p>there might have been but its a blur from here. I just remember that specific question because i spent a while on it and it took me five minutes to solve, while the other ones i just looked at and did without really thinking too much about them</p>

<p>how did you guys do one with the table about the time it takes to construct stuff with the inequalities for the answer. Also for the trapezoid one did you guys get 56 ( i estimated). and ethanking can you explain how you got 2a+2b<a+b+2c on the triangle one.</p>

<p>Crap…i feel like i put cos for that one but i remember doing that question quickly. Whatever everyone thought it was hard so i probably got a 35 with curve</p>

<p>I think it was 2a + 2b>a + b + c because you end up getting a + b > c which is some triangle theorem</p>

<p>2a+2b>a+b+2c</p>

<p>if you cross out he a’s and b’s from both side
you get a+b>2c which is incorrect</p>

<p>a+b>c
2c>a+b</p>

<p>triangle inequality theorem</p>
