<p>@ndl1290 It was 4 sqrt 3 as I posted above</p>
<p>The one with 3 prime numbers a,b,c ab=33 bc=21 abc=?</p>
<p>I got 231</p>
<p>@Light365</p>
<p>The answer was D, whatever that was. The sum had to be 76</p>
<p>@Scarn
I got the same</p>
<p>@Light</p>
<p>29 and 47 I believe</p>
<p>@Light365
It was 29 and 47</p>
<p>All numbers in set x are in set Y</p>
<p>I got c but I have no idea what it said</p>
<p>@MichaelGScarn
It was E. If it’s not in X, then it’s not in Y.</p>
<p>@ Scarn</p>
<p>I put c. It said that if it not in Y it is not in X</p>
<p>@zzzzzz</p>
<p>Y can have all X numbers and any other numbers it wants.</p>
<p>@drac313
If it’s not in Y, it can still be in X… It said all numbers in X had to be in Y, not the reverse.</p>
<p>@drac313
Oh damn I totally messed up that question…</p>
<p>x = [2,4,6]
y=[1,2,3,4,5,6]</p>
<p>That was the set I used. drac313, if that was what c said then I think we’re right</p>
<p>mx+py = 10
mx+x+py = 14</p>
<p>x=4</p>
<p>I had the same thing as Drac as well</p>
<p>The X and Y sets was (C) for sure. (E) is wrong.</p>
<p>@Scarn
Yes that is basically what the statement meant. X is merely a subset of Y, so if Y doesn’t have a number, X can’t have that number</p>
<p>anyone get the one about folding the dotted line to make a cube</p>
<p>The impossible cube one looked like this I think:
<em>X</em>
XXX
X_X</p>
<p>cube dotted line one was d</p>
<p>The answer was definitely C just make your own subsets… Have X be 3 and Y be 2,3 and then you can eliminate every answer except for C.</p>
<p>@kayak48</p>
<p>I think it was E. It was like this:</p>
<p>–[]–
[][][]
[]–[]</p>
<p>Is it okay if you grid in 0.8 instead of 4/5 when it asks for a fraction?</p>
<p>Please answer.</p>
<p>@runner
yeah</p>
<p>@Everyone</p>
<p>It was the one with a flap sticking up and two flaps down. But I think it was C or D if I am not mistaking. We have the same answers but not letter</p>
<p>–[]–
[][][]
[]–[]
was d 100% sure</p>
