anonymous · Answer

The original rectangle has 2 sides of x feet and the other 2 is 4 feet. The equation would be 2x + 8. 2x is multiplying the sides of the frame. The -6 term is added because the frame is not included in the perimeter of the picture.

But what does they all represent?

(2x + 8) - 6 represents the frame not being included.

2x + 8 represents the original rectangle.

2x is the sides of the rectangle needed to be multiplied.
