<span> A. Commutative Property i think, I'm on the same lesson as well:)</span>
This is one proportion that can be created from the given information

.
You would then use cross product to solve it. Also reduce 36/24 to 3/2
3(3x + 7) = 2(6x - 6)
9x + 21 = 12x - 12
33 = 3x I subtracted 9x from both sides and added 12 to both sides
11 = x
H(t) = -16t2 + 186t + 43
at the ground h = 0
hence; -16t2 + 186t + 43 = 0
solving this quadratic equation using the quadratic formula ; a = -16, b = 186, c = 43 ; x = (-b +-(b2 - 4ac)1/2)/2a
gives t = 11.8 seconds to the nearest tenth (note that the negative root has no practical significance)
