Suppose the length of the smaller piece is x inches
Then the larger piece must be x + 6 inches
Since total length is 44 inches, the expression will be x + (x + 6) = 44
after simplifying, you should get x = 19 inches
To verify your answer
Shorter piece is 19 inches so larger piece is 19+6 = 25 inches
adding the two pieces together 19 + 25 = 44 inches
Hope this helps
