<p>damn it... well i guess one wrong isnt too bad haha. i dont care much about math for this test anyway... i just took it to improve CR/W.</p>
<p>i got 3 too... also what'd you geet for meediian it hink its 11 or 12 i wrote 12 but think its 11</p>
<p>its 11, it asked for an ODD interger values</p>
<p>It was 11.</p>
<p>Oh yeah, I got 105 as the answer for something in the Grid-In section.</p>
<p>Yeah 105 was an answer for a geometry problem.</p>
<p>does the SAT take the highest score overall or the highest score in each section if u take it more than once</p>
<p>was the fence post question part of experimental?</p>
<p>No, the fence post was not experimental.</p>
<p>I only had 3 math sections and I had that one. However, if you had the other version of the test then you wouldn't have had it.</p>
<p>no. fence was grid-in. grid-in is never experimental (unless you have 2 grid-in sections.) but i had the fence post also but only one grid in, so if you had 2 grid-ins, then ur experimental is the one without the fencepost</p>

<p>If xy + x^2 = an odd number, then which of the following MUST be true?</p>
<p>I. x is odd II. y is odd III. x + y is odd
</p>
<p>The solution to this problem is simple. </p>
<p>First, observe that x(x + y) is therefore odd (factoring).
Then, observe that for a number to be even, it must have a factor of 2 in it.
Then, observe that the factorization of x^2 + xy dictates that x and x + y must not have factors of 2 in them. (If either of them have a factor of 2, then the whole thing becomes even).
Therefore, x is odd and x + y is odd.
Finally, bubble in whichever answer choice was I and III.</p>
<p>
<p>I said only III... here's why</p>
<p>if x and y are both even, then the expression is even. (doesn't work) if x is even and y is odd, then the expession is odd. (works)
</p>
<p>xy + x^2</p>
<p>even * odd + even^2
even + even
even</p>
<p>Incorrect.</p>
<p>The even/odd question was I and III.</p>
<p>The only combination that works is an odd x with an even y.</p>
<p>Take x=3 and y=4 for example. 3*4 + 3^2 = 12 + 9 = 21 (odd)</p>
<p>I and III is definitely correct.</p>
<p>
Take x=3 and y=4 for example. 3*4 + 3^2 = 12 + 9 = 21 (odd)
</p>
<p>This isn't a solution, it's solely an example...</p>
<p>What was the answer to the question that asked which variable on the number line will multiply to give 1? I put A I think. I put in values and got 1.125, and the rest negative I believe.</p>
<p>For the weird symbol problem I think I got 1/3.</p>
<p>I think the xy odd one answer was D, I and III</p>
<p>Yes. It was definitely I and III.</p>
<p>I was just giving an example of how I and III works. That was definitely the answer though.</p>
<p>can you explain the median one again. i got 12 also but i didn't understand ur explanatiion</p>
<p>waht was the problem with the 2 parallel lines and it asked for the degree measure of Y</p>
<p>and had like two equations... one was like 2x + 10 was it like 75 or somethign?</p>
<p>105 deg (10 char)</p>
<p>105 degrees 10 char? whats char? haha also ii ghouth it was like 65 or 75? but i was really confused on that one... does anyone remember the parallel lines problem and can tell me how to get the asner?.</p>
<p>als o what other probalems did everyone remember taht haven't been discussed yet</p>
