Answer:
Perimeter = 28 + 8x inches
Step-by-step explanation:
Length of the photograph = 7 inches
Width of the photograph = 5 inches
Both the length and width of the frame are 2x inches larger than the width and length of the photograph.
Length of the frame = 7 inches + 2x inches
Width of the frame = 5 inches + 2x inches
Perimeter of the frame = 2(Length + width)
= 2{(7+2x) + (5+2x)}
= 14 + 4x + 10 + 4x
= 28 + 8x inches
Perimeter = 28 + 8x inches
I believe it is C, systematic sampling.
Hope this helps!
