Please do this fast. Put 6/3 6/2 and 6/8 LEAST TO GREATEST. FA!!!

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.

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

Someone which statements are true? check all that apply.
