Question 262355
OK.
Let x=the shorter piece
Then x+1=middle sized piece (we are told this)
And 2x=the longest piece (we are told this also)

And we know that the three pieces must add up to 29 inches.  So our equation to solve is:

x+x+1+2x=29  collect like terms
4x+1=29  subtract 1 from each side
4x+1-1=29-1  collect like terms again
4x=28  divide each side by 4
x=7 in---------------shorter piece
x+1=7+1=8 in---------------middle sized piece
2x=2*7=14 in-----------------longest piece
CK
7+8+14=29
29=29
