a 5 inch x 7 inch photograph is placed inside a picture frame. Both the length and width are 2x inches larger than the width and length of the photograph. Which expression represents the perimeter of the frame?

Answer:

The correct answer is P = 24 + 8x.

Step-by-step explanation:

First, we must express the length and width of the frame.

Length = 7 + 2x

Width = 5 + 2x

The perimeter is the sum of the four sides of the frame.

P = 2 * (7 + 2x) + 2 * (5 + 2x)

P = 14 + 4x + 10 + 4x

P = 24 + 8x

In this way, we express the perimeter (P) of the frame.

Have a nice day!
