<p>Does anyone remember a question with like a 4x+3=7 or something along those lines?</p>

<p>Thanks for making the list guys. Really helps out people who don’t wanna read through 47 pages!</p>

<p>the answer is 4, not 3, for the question with the plane that gives you 4 points with variables. I remember one of the points being (3,1)</p>

<p>wait do you guys have the last problem that asked for the value of a in the quadratic equation? (i don’t remember what i got lol)</p>

<p>What is the 9root 2 question? Also wasn’t there a question with 10 root 2 and another with 4 root 2?</p>

<p>10√2 was a wrong answer choice and 4√2 is on the list</p>

<p>and soccerboi we already have 4 on there</p>

<p>^ soccerboi i think that is addressed in key as “4 (value of z-x)”</p>

<p>i think u shud take the 3 out, i dont know what that is for</p>

<p>48
3/8</p>

<p>What two questions are these for? Someone help please :)</p>

<p>46/54 (add to this if you remember any)</p>

<p>100pi question about circle radius 5 inscribed in triangle inscribed in larger circle.
4sqrt2 </p>

<p>for f(g) = some quadratic equation, g(x) = some quadratic equation. what is the value of a at x=-1 i believe i got 7</p>

<p>im thinking it was
f(x) = x^2 - b + c … f(-1) = 5
g(x) = ax^2 -b + c … g(-1) = 1</p>

<p>*correction sorry I just realized you already have this on the list lol</p>

<p>46/54 (add to this if you remember any)</p>

<p>100pi question about circle radius 5 inscribed in triangle inscribed in larger circle.
4sqrt2 </p>

<p>4.5 (a^2+b^2 question)
70 for the value of x (it gave a 140 degree vertical to two x’s so x=10)</p>

<p>can someone explain these two in more detail? dont seem to recall them</p>

<p>also what do u mean “45/120 histogram of book each equaling 10 or 5”</p>

<p>how can we be missing 8? must have been the easy ones</p>

<p>Yeah probably easy ones that have slipped our memories. So far I have only missed one or two (it better not change and they were really dumb errors)</p>

<p>^yeah same</p>

<p>iceberg the histogram one showed a chart with books, remember?</p>

<p>i dont remember the 70 degree one either</p>

<p>the median one was x=2? ■■■… i must have forgot the “2x” part so I put x=5…is that why i put 5?? :confused: that’s the one i missed…</p>

<p>I also think I missed that one (although I may have gotten it right, I dont really remember) for some reason i think i put 5 as well</p>

<p>what was the 70 degree one iceberg mentioned?</p>

<p>what is the 4.5 (a^2+b^2 question)?</p>

<p>it had the intersection of two lines, gave an angle of 140, across from that was divided into two equal angles (x), and asked for the measure 140/2 = 7</p>

<p>a^2+b^2=20, ab=8, what’s (a+b)^2/ab ?</p>
