Help with a geometry question please! Thank you.

8000 + 8800 + 8000 + 8 million + 80 trillion + another a katrillion equals

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

The height of a flare fired from the deck of a ship in distress can be modeled by h(t)= -2(8t^2-52t-28), where h is the height of the flare above water and t is the time in seconds. a. find the time it takes the flare to hit the water.
