The length of a sandbox is three feet longer than its width. Write the expression that would represent the perimeter of the sandbox.

4w + 6

Step-by-step explanation:

Let width = w

Length = w + 3

Perimeter = 2*length + 2* width

                = 2(w +3) + 2w           {Use distributive property}

                = 2w + 2*3 + 2w

                =  2w + 6 + 2w              {Combine like terms}

                = 4w + 6

step-by-step explanation:

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
