The speed of the airplane is 90 miles per hour and the speed of the wind is 30 miles per hour.
<h3>Relative Speed Concept;</h3>
When the plane flies against the wind;
- Relative Speed = 120 = x -y
When the plane flies with the wind;
- Relative Speed = 240 = x +y
Where in;
- The speed of the air plane = x
- The speed of the wind = y
By solving the equations simultaneously; we have;
- x = 180 miles in 2 hours and y = 60 in 2 hours.
Ultimately, the speed of the airplane is 90 miles per hour and the speed of the wind is 30 miles per hour.

You would need to put 4 in for (n)so, 5(4)+8 then solve. 5 times 4=20 plus 8 is 28. I hope I could help!
F x G (x)
(2x + 8) x (6x + 6)
12x^2 + 12x + 48x + 48
12x^2 + 60x + 48
x^2 + 5x + 4 (Answer)
Hope this helps
