<p>9 radical(x) + 7 = 16, what is the value of x?</p>
<hr>
<p>(x+y)/(x-y) = 7, what is value of x/y?</p>
<p>x = 1/2
y=1/3
Add those together. Explanation? Uh, I'm not really sure I just noticed if you multiply it by itself one more time it becomes that fraction of itself...if that makes sense. I'll tackle the next ones in a second.</p>
<p>good job...that's how you should think.</p>
<p>5 = m^x, what is 5m?</p>
<p>m^(x+1)
m^(x+2)
m^(x+5)
m^(5x)
m^(2x)</p>
<p>^^^Do those mean something??</p>
<p>those are the answer choices...A - E...pick one</p>
<p>9 percent less? For the areas of the rectangles.</p>
<p>Well then to get 5m on the left you need another m on the right so A is the anwer.</p>
<p>you are on a roll keep going...I see an 800 (MATH) kid here... =)</p>
<p>For the prism, just do pythagorean a few times, right? That doesnt give a clean answe so maybe im doing it wrong, but sq root of 189 which is like 13.747</p>
<p>well yeha you could do that or use this formula....Radical (height ^ 2 + length ^ 2 + width ^ 2)</p>
<p>for a cube it would be radical (3 (side) ^ 2)</p>
<p>make sense...try it? its a lot better than the pythag. stuff.</p>
<p>I know for sure I got one wrong in June. Stupid skid mark question/bad pacing. I tried to do it in like 30 seconds and set up the equation wrong. Hopefully one wrong is an 800 (PLEASE!)</p>
<p>true...yeah it was 1/9? right...i got like a long decimal .1111 and I had like 20 seconds and I guessed 1/9...didn't have time to think too mcuh lol...but got it right. I got one wrong in experimental so I'm happy.</p>
<p>Yeah 1/9. I put 3 in a wild guess after I realized I set it up wrong. If I had just read the problem over, I would have known 3 would not make any sense at all.</p>
<p>lol its all good...wait it was multiple choice right? or was it grid in?</p>
<p>do you rmbr the exact equation by any bizarre chance?</p>
<p>4/3 by pure guessing for the (x+y)(x-y) and the oen before that x=1</p>
<p>Someone posted almost the exact wording in one of the post-test discussions. It was multiple choice. Choices were like 3,1/3,1/9 i dont remember what else.</p>
<p>nice job. you did good. now think about it...these questions were prolly the "hardest" I could find in the KAPLAN 8 test book and compared to the real thing...man they do NOT COMPARE. the real thing has some fairly time consuming questions in the end.</p>
<p>the (4-p)(4-p-x) parabola thing almost tricked me. I just plugged it into my graphing calculator though and changed the constant for p and i kept getting -4.</p>
<p>yeah it was -4. I did the same....it was kinda scary to put -4 since it was in the answer but the SAT considers these "hard" questions for the average person lol so yeah this was def.. -4...I tried it afterwards with all different numbers and it works -4.</p>
<p>If I had tried it to make sure a few less times, I would have had more time for the skid mark problem....</p>
