A heart shaped chocolate box is composed of one square and two half circles. The total number of chocolates in the box is calculated by adding the area of
a square given by 4x^2 and the area of a circle approximated by 3x^2. The company
plans to add a small additional box for a promotional campaign containing one row
(2x) of chocolates. If the total combined heart shape and small box contain 69
chocolates, which of these equations could be utilized to solve for the number of
chocolates in the small box (2x)?
