To find the average speed of the jet, we divide 4000 by 5. When we do so, we get 800. Therefore, the average speed of the jet was 800 kilometers per hour. Hope this helped!
6. Factor 4x from 22x2 + 40x 6.
is that multiply 4x 22x2 +40x6
(9/14)*6x = (27/7)x
And that is reduced by 10, then...
27/7x - 10
