Answer:
2
Step-by-step explanation:
even tho this is a very hard question it is 2.
Let J = rate of jet in still airLet W = rate of wind Distance formula: d = rt / r = d/t Flying against the wind the jet flies at a rate of J - W = 1860 miles/3 hours = 620 miles per hourFlying with the wind the jet flies at a rate of J+W = 9180 miles/9 hours = 1020 miles per hour The average of these 2 rate is the speed of the jet in still air J = (620+1020)/2 = 820 miles per hour J - W = 620
820 - W = 620
W = 820 - 620 = 200 miles per hour The jet in still air flies at a rate of 820 mph(miles per hour)The wind speed is 200 mph(miles per hour)
Answer:
39 is the 13th term
Step-by-step explanation:
Okay so essentially the 
is just a substitute for x.
See how in the equation they put n into the x spot:
They changed the variable names:
Now we know what the n actually means, plus when they ask about the terms youre trying to find it's based off of that n:
When they say, 13 term, they mean 
which would be the 13th answer in the series. So the first term would be based off of 
So whatever number is in the n position by a is what you'll be plugging into the x spot.
These are all the answers leading up to the 13th term they asked for, and you can continue thus same equation with whatever number you can put into the n space.
Area of a square:
(x-2)(x-2)
=(x-2)^2
=x^2-2x-2x+4
=x^2-4x+4 unit sq
