The length of the sides of a square are initially 0 cm and increase at a constant rate of 7 cm per second. Write a formula that expresses the side length of the square, s (in cm), in terms of the number of seconds, t , since the square's side lengths began growing. s = 7t Correct Write a formula that expresses the area of the square, A (in cm2), in terms of the square's side length, s (in cm). A = s^2 Incorrect s 2 syntax ok Write a formula that expresses the area of the square, A (in cm2), in terms of the number of seconds, t , since the square started growing. A = Incorrect Suppose the function f determines the area of the square (in cm2) given a number of seconds, t , since the square started growing. Write a function formula for f . f ( t ) =
