A plane traveled 1290 miles with the wind (downwind) for 3 hours. Then it traveled 1576 miles against the wind (upwind) for 4 hours. Find the speed of the plane in still air and the speed of the wind.

Which function in vertex form is equivalent to f(x) = x2 + 6x + 3? f(x) = (x + 3)2 + 3 f(x) = (x + 3)2 − 6 f(x) = (x + 6)2 + 3 f(x) = (x + 6)2 − 6
