<p>keep em coming guys add on</p>

<p>Anyone remember one where it said 0<j<k<6, and you had to pick which could be a product of j and k. Was the answer 20?</p>

<p>Nvm. I solved it. The equation was (x+a)(x+2b)=x^2+4abx+b^2
What I did was equate 2ab to b^2 which would mean 2a=b. Then it’s just algebra from there. Too bad I thought of this as I ran out of time. Oh well, I’m pretty sure that it was experimental, otherwise people would definitely be asking about it. At least my mind is at peace =] For anyone that wants to know the answer: a=0,5/8. But then I think the problem said a and b were integers so a=0</p>

<p>@Linger: Yeah. Possible answers are 2,6,12, and 20. 20 Was the only one on there</p>

<p>Dice one was 1/54. End of discussion.</p>

<p>1/54 for the dice one (4 possibilities: 666, 665, 656, and 566, out of 216); </p>

<p>the choice for the x sqrt 3 and y sqrt 5 comparison was actually “x^2 > 5/3 * y^2”, not “x^2 > 3/5 * y^2”</p>

<p>I don’t remember putting an answer of 1080. What was the question?</p>

<p>total hours studied in high school</p>

<p>You probably misread the part where it said WEEKLY average or made a stupid mistake adding or something.</p>

<p>Are you sure parallel lines was 1 and 2? I got just 1.</p>

<p>i got 1 and 2 because the other one was perpendicular, or someti9hgn like that.</p>

<p>i got 5400 for hours studied in high school (choice e)</p>

<p>I got parallel lines I and II. I drew it out on my test booklet ftw.</p>

<p>It was I and II for the lines. I was that two lines were perpendicular, which was true. II was that two lines were parallel, which was also true. III was that two lines were perpendicular, which was false since they were actually parallel.</p>

<p>oh… **** my life. I thought all answer choices asked if they were parallel.</p>

<p>so what was the answer for hours studied?</p>

<p>1080 hours studying (or doing homework, whatever.)</p>

<p>Was that 1080 question a grid-in? I don’t really remember it.</p>

<p>how’d you get that answer?</p>

<p>Anybody remember a question where it gave (1+x)(1+2x)=k</p>

<p>then is said what does (1+x)(2+4x)=?</p>

<p>It was 2k right?</p>
