The answer should be 9 rounded because 2 pi r 56.5 will give u that.
4n, 6b, and -8 are the terms
Let C be the number of cats and B be the number of birds.
Each cat has 4 legs while each bird has 2 legs. Thus,
4C + 2B = 22
2B = 22 - 4C
Each cat and each bird has 2 eyes
2C + 2B = 16
Substituting 2B
2C + 22 - 4C = 16
2C = 6
C = 3
2B = 22 - 4(3)
B = 5
2 cats and 5 birds
7.81 then 7.14 then 7.081 then 7.002
