A5 inch x 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches larger than the width and length of the photograph. Which expression represents the perimeter of the frame?

8x+24

dimensions of the photograph  

length - 7 inch  

width - 5 inch

dimensions of the photo frame is 2x larger than both width and length  

length - 7 + 2x

width - 5 + 2x

the perimeter is sum of all 4 sides  

Perimeter = 2(7 + 2x) + 2(5 + 2x)

                = 14 + 4x + 10 +4x

                = 24 + 8x

correct answer is 8x+24

the answer is a beach is the best place to be
