The upper left-hand corner of a piece of paper 8 in. wide by 17 in. long is folded over to the right-hand edge. How would you fold it so as to minimize the length of the fold? In other words, how would you choose x to minimize y?

    Where do x and y enter the picture ??

  2. Rachel

    if you fold it it will create a right triangle. x is the base and y is the height.

    Here is a solution to your problem, with sides 6 and 12
    I suggest you print out the solution and change the constants to yours.
    I suggest you are careful that your base of x, and height of y are consistent with the x and y in the solution
