Respuesta :

since you dont know the integer lengths of the pieces the length of the other piece would be   15 - x   feet

Answer: The required expression would be,

15 - x

Step-by-step explanation:

Given,

Total length of the board = 15 foot,

If it is cut into two pieces,

Such that, the length of one piece = x feet,

Therefore,

The length of other piece ( in ft ) = total length - length of one piece

= 15 - x

Which is the required expression.
