    Sorry about this if it isn't allowed. But I'm on my chapter closure for Geometry and I can't figure out this one last problem. It would mean a lot if someone could help me out (I even called my study group. But it's filled with retarded jocks and dumb blondes who either said bullshit or just laughed and hung up.)
    I would also like an explanation if possible so I get this down for the test on thursday. Math is definetly not my strongest subject, but I'm trying.

    -2+11x *-4+3x=?

    Not a cheater. Just someone asking for help. I'm obviously asking for an explanation so I know how to do this kind of problem from now on.
    If I was cheating I would've just called up one of my friends and asked them what they got. But I'm a bit more respectable then that.

    Vexza- yes.

    I'll try and draw the picture on MS paint since my scanner is at my grandmothers.

    The equation is incomplete. Without knowing any of the boundary conditions, x could equal anything.

    If we're able to set the equation equal to 0, then we're able to find out that X must equal 2/41 . But with that question mark there, X can equal anything, and that question mark will simply be the result.

    Are you sure you wrote the question right?

    -2 + (-4*11x) + 3x = ?

    How easy WAS math when you were in high school? Because even my parents were totally clueless when they saw this.

    There was a similar problem which I totally guessed on. Maybe someone here could tell me if I got it right.

    11*3x=33x

    Oh, squares.

    ...

    Why is this near-essential skill so tedious?

    11*3x is definitely 33x.

    Oh, ok. So are we to assume this is a square? In which case,

    3x-4 = 11x -2 as l=w

    so a little algebra, and x= -2/8 = -1/4

    meaning area is l*w = (-3/4-4) * (-11/4-2) = -4.75^2 = 22.5625

    Its a little strange, since you end up with negative side length, which is impossible in the real world.

    Isn't it l*w?

    What I really need to know is if you add x + a negative or postive, what will that come out as?
    Like would 2x+4= 6x, or 6?

    I'm not saying that's wrong. It just seems a little more complicated then it should be, since all the other problems were much more simple and easy to figure out.

    What he's saying is that if you assume the length is equal to the width, you can determine the value of x. Once you know the value of x you can then determine the area of the square (length * width)

    Don't feel bad about it, IIRC Aernaroth and I have both taken a lot of advanced math courses.

    This is why I went to med school. I suck at math. Hope this helped the original poster!
