A 10-foot board is to be cut into 3 pieces. Two of the pieces will be the same length and one piece will be 2 feet longer than the other two.

Which equation could be used to solve for the lengths?

x+x+ 2x= 10
x+x+x- 2 = 10
x+x+x= 10 + 2
x+x+x+ 2 = 10

anonymous · Answer

Two pieces are the same, then x+x (if one of them is x)
The third piece is x+2, then total length is x+x+x+2=10
