The rectangle shown has a perimeter of 52 inches.
a. Write an equation describing the possible values
of x and y.

Step-by-step explanation:

If x and y are the lengths of the sides in inches, and  p = perimeter,  

The formula is:

p+=+2x+%2B+2y

given:

p+=+52 in

2x+%2B+2y+=+52

subtract 2x from both sides

2y+=+-2x+%2B+52

divide both sides by 2

y+=+-x+%2B+26

Hope this helped! :)
