The table shows the side lengths and perimeters of four squares. Side Length x Perimeter y 4 point 5 18 8 point 5 34 10 point 2 5 41 13 point 7 5 55 Which equation represents the relationship between the side length, x , and the perimeter, y ?
B
y is equal to x minus 13 point 5C
y is equal to 1 fourth xD
y is equal to x plus 13 point 5For a square, the perimeter is four times the side length. The table confirms this: when x = 4.5, y = 18, and 4 × 4.5 = 18, so the relationship is y = 4x, or “y is equal to 4x.”
