X - y = 2400/6 = 400 where x = speed of plane and y = speed of wind.
x + y = 2400/5 = 480 - flying with the wind
adding the 2 equations
2x = 880
x = 440
Speed of the plane with no wind = 440 mph
2x
so...
2x (4t - 2 - 9)
2x (4t - 11)
Hope this helped!

So 6^2 would be 36 because it is 6 times 6 and then -4 so 36-4=32
Hi!
For this equation, you can solve it by using the quadratic formula:
x=-b<span>±sqrt/b^2-4ab
