Question

A5 inch x 7 inch photograph is placed inside a picture frame. Both the length and width of the frame are 2x inches larger

Answer 1

Answer:

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
