Can someone help me with this​

What are the steps to solving the inequality 3b + 8 ≥ 14?

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

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.
