Afalling object travels a distance given by the formula d=2t+6t2, where d is measured in feet and t is measured in seconds. how many seconds will it take for the object to travel 60 feet? round the answer to 4 decimal places.

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
