    Is the Quadrangle in the Geometry Challenge a Square?

    Yeah, sure, I miscounted the coefficients.

    Is the Quadrangle in the Geometry Challenge a Square?

    Am I wrong or I can divide this equation by (y-1)?

    Is the Quadrangle in the Geometry Challenge a Square?

    Ok, by doing the algebra I found the equation on the pic. I don't know if this was right, so I went to Wolfram to solve this.

    Is the Quadrangle in the Geometry Challenge a Square?

    Just another doubt, how can I know if the biggest triangle (1, 1+x, 1+y) has a 90º base angle? Because it wasn't specified in the problem if there is a square.

    Differculty working out what is doing work in a mass attached to a spring system

    I just don't understand something in your problem: when you said you put up a Force of 50N , this is the Resultant Force (150N [yours] - 100N[m.g] = 50N [Resultant Force]), or it is the Force you are applying? Because if you apply a Force of 50N to an object under 100N vertically, it won't move...

    Yeah, I think that's the point.

    Is the Quadrangle in the Geometry Challenge a Square?

    Yes, in this case x=y^{-1}.

    Is the Quadrangle in the Geometry Challenge a Square?

    Well, I found this challenge in another forum (not about math) on the internet, and, originally, there were no 'w', 'z' or 'y' drawn on the pic, it was just "find the x", but I put them on because I know you guys probably would create other variables to solve the problem. Another problem I had...
