<p>Okay...for that teacher one I put the one with "personal" or something...It seemed logical but I really couldn't focus, especially on that question.</p>
<p>So did anyone else not have "harrowing" and "disingenuous"?</p>
<p>no...it was "The beaches were contaminated with sewage flowing from the chemical plant; the contamination lasted for several days"</p>
<p>otherwise it could have been the sewage flowed for several days</p>
<p>ok for that one the equation was x^2 = x + 6, so x cannot be greater than 3 because otherwise there would be no equation. All the other choices worked when i plugged them into the equation.</p>
<p>@MattM</p>
<p>i didn't get those words either</p>
<p>@Goldfish</p>
<p>-2 was a solution for x...therefore... x cannot be greater than 3 if a negative answer was also a solution for x</p>
<p>I didn't have harrowing and disingenuous"</p>
<p>i'm pretty sure there was no mention of a "chemical plant" and that after the semi-colon there was a "this" ... except for that, i don't quite remember the details.</p>
<p>I still think we may have not reached the correct original sentence (to clear it up). I would find it unusual for me to make little errors on writing since it is my strong point by far. But the last two I did instantly so maybe, just maybe, I got that one wrong.</p>
<p>Goldfish, what do you mean. Can someone explain this to me?</p>
<p>well two of the choices were...</p>
<p>x^2 > x
x^2 < x</p>
<p>We are given x^2 = x+6</p>
<p>I think one of the two choices i mentioned is correct?</p>
<p>In any case, apart from the exacting wording of the sewage sentence, i think we agree that the answer is E.</p>
<p>The sentence read something along the lines of....</p>
<p>Sewage waste ....... the ocean, which can last for several days. This is not correct because it's a misplaced modier...the ocean doesn't last for several days. I think I ended up putting E... with the semicolon.</p>
<p>I had 2 math 20 question sctions. Which was experimental?</p>
<p>foolonthehill, yeah, I got the firfst choice you listed.</p>
<p>"well two of the choices were...</p>
<p>x^2 > x
x^2 < x</p>
<p>We are given x^2 = x+6</p>
<p>I think one of the two choices i mentioned is correct?"</p>
<p>what do you mean? x equals wasn't an answer i think. i only saw x<3</p>
<p>Does this thread also make you all feel like you've done worse than you originally thought? :)</p>
<p>We are given x^2 = x+6 in the problem.</p>
<p>edit:
The choice x<3 implies that x cannot be 3. However, x=3 is a solution for the polynomial.</p>
<p>x^2 > x is what i answered.</p>
<p>The question is:
Which one of the following is correct, given the equation x^2=x+6
If you solve for x, you get x=3, -2
Therefore the only correct answer is x^2>x</p>
<p>Golfish, it was x^2>x</p>
<p>Just solve the equation and you come out with X=-2, therefore if you square that you come with 4 and -2+6 is also 4, making the equation valid.</p>
<p>...</p>
<p>the problem was</p>

Which of the following is true if you are given:</p>
<p>x^2 = x + 6</p>
<p>A)
B)
etc.

</p>
<p>correct answer is x^2 > x</p>
<p>because x = 3 was also a solution for x</p>
