<p>hyakku......</p>
<p>so what about the (X=y) (x-y)....</p>
<p>yeah that one...crap i don't want to embarass myself with my answer (if i can even remember it)</p>
<p>I put x=y because x-y can only be zero that way, but x^2= y^2 makes sense too</p>
<p>i put down x=y (i hope, i can't remember most of my answers) b/c i split (x^2-y^2) into (x-y)(x+y) </p>
<p>So then we end up with: (x-y)(x+y)(x+y) or something like that. </p>
<p>Let's hope we get it right when December rolls along</p>
<p>Thanks assasin that makes me feel better :)</p>
<p>I got 30 for the wiper fluid b/c:</p>
<p>it said like he had 24 ounces, and needed to have and adequate amount for summer and winter.</p>
<p>Summer is: 1/4?
Winter is: 2/1?
So I divided 24 by 1/4 (Which is 4) and got 6. And then...
I'm not sure, but I got 30 somehow, and I don't think its by adding it onto 24.</p>
<p>yeah, its 30 because one of the other answers was 36, which was supposed to be the trick answer (6 + 30)</p>
<p>Yup, I got 30 for that one as well.</p>
<p>And for the (x-y)(x^2+y^2)=0 or something like that, the answer was x^2+y^2.</p>
<p>x doesn't have to equal y, because 1 does not equal -1, but that still works. x^2 does have to equal y^2, because any negative signs would then be gone, so the numbers would become equal.</p>
<p>oh well, I guess I got that wrong :(</p>
<p>PSATs are ***</p>
<p>now I have a 740, I know I didn't get anything else wrong...</p>
<p>i hate you naidu</p>
<p>can someone explain the sunday one to me... i got 24th, cause isnt the max number of days 31, and 31 -7 equals 24???</p>
<p>why is that, assassin?</p>
<p>M (1) Sunday(7)
M(8) Sunday(14)
M(15) Sunday(21)
M(22) Sunday(28) -> can't be because this is the 4th sunday</p>
<p>I got 21 b/c sunday is the last day of the week and the third week is 21. That, and I made a mini calendar</p>
<p>I made a calender too, haha.</p>
<p>(x-y)(x^2+y^2)=0
simplifies to (x-y)(x+y)(x-y)=0
So x=+y or x=-y... either way x^2 = y^2.</p>
<p>oh...oopsie, i made a b00 b00 lol</p>
<p>I hate myself right now, I am going to get 74 on math, that is my best subject and an 80 in writing? I suck at writing!!!!</p>
