Answer:
x = -3/2
x = -1/2
Step-by-step explanation:
4x^2 + 8x + 3
4x^2 + 2x + 6x + 3
2x(2x+1) + 3(2x+1)
(2x + 3) (2x + 1)
x = -3/2
x = -1/2
<span>distance=6390km; time=9 hrs; rate=710kph
With the wind Data:
distance=5150km; time=5hrs; rate=1030kph
EQUATIONS:
airspeed+jetstream=1030
airspeed-jetstream=710
Subtract these equations to get:
2jetstream=320kph
jetstream=160mph </span>
