If y = 6x − 3, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs? (4 points) {(0, 3), (−2, 15), (4, 21)} {(0, −3), (2, 9), (4, 21)} {(0, −3), (2, 15), (4, 21)} {(0, 3), (1, −9), (2, −15)}

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
