Question

The perimeter of a triangle is 39 inches. If the length of the shortest side is 1/2 the length of the longest side, and the length of the third side is 1 less than the length of the longest side, what is the length of each side?
If x is the shortest side and y is the longest side, one equation is
a. x y z=39
b. 2x+2y+2z=39
c. x+y+z=39
d. 1/2xyz=39

Answer 1

let x = length of longest side

1/2x + x-1 + x = 39

Answer 2

? That doesn't match up with a. b. c. or d. though :/

Answer 3

@petewe you there?
