<p>I’m fairly certain it was ab-c=0, not to sound like a jerk or anything.</p>
<p>@rawk
yea u=5</p>
<p>Yes, SAH! Now I am happy again! I am feeling quite bipolar.</p>
<p>Rawk: Yeah. The side of the square (10) formed the hypotenuse of a 30-60-90 triangle, so u was 5.</p>
<p>nah i got k-2 for ex. the AVERAGE of 5 consectutive integers so i picky 33,34,35,36,37…what is the lowest integer and thats k-2…35-2=33.</p>
<p>III worked. If you solve it in variables and take out c by substituting c with equivalent expressions of a and b, it is equal to -2ab. The answer is II and III only.</p>
<p>I think about 95% of my posts came from talking about the test today. Which is weird because this is my seventh standardized test (3rd Sat, took 5 subject tests and 2 acts)</p>

Yeah, that’s sort of what I’m wondering. I’m slowly starting to think it was ab-c=0, though. But who knows? We’ll find out for sure who’s right on the 24th. :)</p>
<p>for those who had the same test as me
did you have a question that had something like (8s^(3))^1/3 = 2y
did you get 1?</p>
<p>Rawk: I think it was 1/8. </p>
<p>Cube root the left hand side and get 2x-1=2y. Divide by 2 to get x-1/2=y. Shift the variables around to get x-y=1/2 or x^3-y^3=1/8.</p>
<p>DAMNITTTTTTT
i forgot to put the 8 over ):
-3</p>
<p>clarification…
ab+c=0
(ab+c)^2=0</p>
<p>(a^2)(b^2)+2abc+c^2=0</p>
<p>subtract the middle term</p>
<p>question about t, t+5, t+10…</p>
<p>what is the difference between the 20th and 19th terms
5 right?</p>
<p>unless i hvae the question wrong, that was the answer. A) 5</p>
<p>i got 5 as well.</p>
<p>Shapiro: hee hee. You’re not the only one feeling bipolar about that question. Too bad we can’t both be right :(</p>
<p>for the t, t+5, t+10 problem, the question gave you the answer…i dont even understand how that was a math problem</p>
<p>I had the version with the dog going through the doors. Anyone know if the section with the 100 to 200 inclusive was experimental or not?</p>
<p>What was the answer and remind me what the choices were please</p>
<p>100 200
101 111 121 131 141 151 161 171 181 191
(111) 122 133 144 155 166 177 188 199
110 (111) 112 113 114 115 116 117 118 119</p>
<p>I had 29 from this</p>
<p>Well, good luck to you. (not really I hope I get it right and you get it wrong :))</p>
<p>equations:
- ab + c = 0
- (a^2)(b^2)+(c^2)=-2abc </p>
<p>1) ab = -c
a^2b^2 = c^2</p>
<p>2) (a^2)(b^2) + (a^2b^2) = -2abc
2a^2b^2 = -2abc</p>
<p>1) ab = -c
c = -ab</p>
<p>2ab(-c) = -2abc
-2abc = -2abc
III works as well as II.</p>
<p>was 302 a answer for grid in too?</p>
