**Reiny**, Friday, January 20, 2012 at 10:20amshortest side ---- x

longest ----- 2x + 10

let middle side be y

2x + 10 = x + y -6

y = x+16

so x + 2x+10 + x+16 = 54

4x = 28

x = 7

shortest side = 7

longest side = 24

middle side = 23

check: is the sum = 54 ? yes!

is 24 equal to 6 less than 30 ?, yes

is twice 7 10 less than 24 ? yes!

All is good!
