Answer:
See the attachment. (All results are integers, so are correct to 6 decimal places.)
Step-by-step explanation:
The function simplifies to ...
... f(x) = x(x-9)/((x+1)(x-9))
... f(x) = x/(x+1) . . . for x ≠ 9
150 because if it is going 420 in 14 hours you divide 420 by 14 which gives you 30 and then you multiply 30 x 5 and you get 150 so the bird goes 150 miles in 5 hours
Its below!
a=l*w
9=(3+x) (2+x)
9=6+3x+2x+x^2
9=6+5x+x^2
3=5x+x^2
Hope this helps!! :)
