Wait are you sure? I thought that was if the x was in the abs value?</p>
<p>It was definitely only one solution since the absolute value was around the -2.
I’m 100% positive.
Youre thinking about if the x was in the absolute value, but in this case it was only -2 and in that case the solution will always be equal to 2.</p>
<p>The easiest thing to do for that problem was to graph it…it was “A”.</p>
<p>P.S. what score do you think a -4 would be for the math?</p>
<p>I’m pretty sure it applies to all real numbers.
[Absolute</a> value - Wikipedia, the free encyclopedia](<a href=“http://en.wikipedia.org/wiki/Absolute_value]Absolute”>Absolute value - Wikipedia)</p>
<p>The absolute value of -2 is just 2 and that is what your equation is set equal to. So there is only 1 soln if you solve for x. It was trying to make you overthink things probably</p>
<p>you are right in that usually absolute value stuff has two solutions, and i originally thought it was 2 as well…
HOWEVER</p>
<p>if you say l-2l= 2x+1
ur right that that leads to two equations: -2=2x+1 AND -2=-2x-1</p>
<p>But if you solve both of these for x you get x= -3/2 and x=1/2
and if you plug in both of those, x=1/2 works with the original equation but x=-3/2 doesnt because l-2l = 2(-3/2)+1
l-2l = -3+1
l-2l= -2 which is false…</p>
<p>on wikipedia it says any real number a lol</p>
<p>so only x=1/2 works, thus one solution</p>
<p>Guys don’t argue about something so stupid… he’s trolling. The answer is definitely 1.</p>
<p>What other problems from 40-50 do you guys remember.</p>
<p>You guys are way over thinking this. Haha the absolute value was only around -2; which by law always equals 2. That simple.</p>
<p>Does anyone remember the answer to the perimeter of the Square Pyramid? I put 14, I wasn’t exactly sure though. I used the Pythagorean Theorem to find the slanted sides, which ended up being the sqrt(2). Then I multiplied the base, which was 2, by 4 to get the perimeter of the base, and then I multiplied the the sqrt(2) by 4 because there are four sides leading up to the tip of the pyramid. Then adding 4<em>2 and 4</em>sqrt(2) equaled about 13.6. I rounded after that and put it, but I wasn’t sure if I was right.</p>
<p>Wait do you even know what trolling is? LOL</p>
<p>I don’t think you should be allowed on the internet if you think I was “trolling”.</p>
<p>And maybe I’m wrong, but lets say you move all the parts of the equation to one side, making it something like l-2l-2x+5=0 or whatever. I don’t think its correct to only chance the -2 into a +2.</p>
<p>It was also a late 40 early 50 question so it could’ve been tricky.</p>
<p>nonono brobrobro it gave you the slant heights at sqrt3, gave you the base as 2 which you divide by 1 and then yous see a 30 60 90 triangle, which means the slanted edges are 2 since in a 30 60 90 triangle the hypotenuse is 2x the smallest side, so it think it was 16.</p>

eh sorry dude it was counting on high-level thinkers like you to overanalyze it, but nbd you probably did better than me</p>
<p>@Lolol
I put 16</p>
<p>yeah square pyramid was 16.</p>

<p>there was nothing tricky about it…</p>
<p>hahaha its okay i freaking bombed reading, and maybe i did over think that, and in that case i think im -3 -_- hoping the curve is like october -2 was a 36 -3 was a 35 LOL</p>
<p>there was one about like 6x/8x^2 or something and i chose x had to be rational was that the answer</p>
<p>it was 4x/6x^2, and the answer was 2/3 i think. because it wasn’t asking about what the answer would be, the question was like: what does x have to equal in order for the expression to be a rational number? and it was irrational no matter what unless you plugged in 2/3 for x. maybe it wasnt 2/3 i forget but the answer was D/J</p>
<p>idk can someone back up on this because i thought it was asking if the first is rational what is x but i dont really remember you may be right</p>
