write an expression for the width of the box in terms of x the it started out a rectnagle piece of cardboard and it is 12 inches width and 12 inches length

Answer 1

I assume what you mean here is it started out as a 12 by 12 piece of cardboard and you cut two squares of length and width x out of it and folded up the sides to make a box. An expression for the width and length would be 12-2x.
