Math Questions Compilation for the test with writing experimental

<p>@Butternut: nope, I still have to wait 60 seconds...</p>

<p>that x, y, and z one
I got abs(x-y) as the largest value</p>

<p>abs(x-y) because x=81 and y=-21</p>

<p>That's what I got.</p>

<p>There was one that was y=(x+a)(x+b), and c=? I had 17. (possible grid-in?)</p>

<p>Possibility grid in -> 23</p>

<p>hm? What was the question for that?</p>

<p>I remember now:
y=(x+a)(x+b), 7x^2+cx+6, and c=?</p>

<p>I got 17 with a=2 and b=3</p>

<p>It was (x+a)(7x+b)=7x^2+cx+6, so expanding we get 7x^2+7ax+bx+ab
Equating the constant term I got a=2 and b=3, (It probably would work with a=3, b=2 and a,b=1,6) and so 7a+b was 17</p>

<p>Okay, I think 17 can do too. I used a=3 and b=2. Anyways, I'm going to bed. Good night.</p>

<p>i had 4 math sections...do u guys know which one was the experimental??</p>

<p>Oui, I got 17 too!</p>

<p>What about the circles one, the last MC question in the grid-ins math section? I got r*root 3...</p>

<p>that's correct</p>

<p>Yay! :)</p>

<p>Thanks dude!</p>

<p>^ Got that one too.</p>

<p>WHY IS NO ONE TALKING ABOUT THE TRAPEZOID-RING QUESTION?! The people in my room were panicked during the break because of that question.</p>

<p>DID YOU GET 18?</p>

<p>Wait, people with different experimentals had different math sections?</p>

<p>Yeah I got 18 for the trapezoids. It was easy (or so I though)!</p>

<p>I thought it was easy too. But then again, I'm a good mathematician :) The guys in my room must have just been stupid (not uncommon)</p>

<p>Hehe. I know this is unrelated, but what do you expect the CR curve to be? (I'm expecting 4-5 wrong)</p>

<p>yeah... i'm sure it is 18</p>

<p>Did everyone get the same math sections? cause we didn't have the same CR sections in different parts of the world</p>

<p>No the math sections are also different across the globe.</p>
