    Setting area = perimeter of rectangle, does it have any meaning?

    To clear this up for you: In most shapes/cases the area does NOT equal the perimeter xy = 2x + 2y, substitutes for most x's and y's do not satisfy the eqn BUT in some shapes where for e.g. the side length is 4, the area will satisfy the eqn, hence perimeter = area. It is in this sense...

    Proving v=w using Vector Space Axioms

    yeah it satifies the 10 vector axioms, but i can't seem to muck around with the axioms to solve the problem. Yeah sorry i meant v + x = w + x I know it has something to do with the 0 vector. ie 0 = +x -x When i incorporate that into the eqn i get v +x -x +x = w +x -x +x ... which I am not...

    How can I prove that v and w are equal if v + x = w + x?

    Here you go Brandy: 0 x u = 0 + 0 x u = -u + u + 0 x u = -u + (1 + 0) x u = -u + 1 x u = -u + u = 0 And maybe you can help me with this one. v + x = w + x Prove v = w

    Proving v=w using Vector Space Axioms

    Homework Statement V is an arbitrary vector space and v,w,x are part of V such that v + x = w = x Use vector space axioms to prove v = w I've looked at the axioms for an hour and can not get any lead to start this question.
