the function for the perimeter of a rectangle is given as P=4x+6

a) Give an expression for the length of the rectangle in terms of the width.

b) If the width is half the length, state a function for both the width and length describing the domain for which these fuctions exist.

  • math b -

    a) If P = 4x + 6, since P = 2L + 2W, then the two sides will be W = x and L = x +3.

    b) W = 1/2 L = 1/2(x + 3)

    I hope this helps.
