Algebraic
Square roots are rational and it equals 5 and 5 is rational
Answer:
<u>6 kg</u>
Step-by-step explanation:
J = mass of nuts gathered by James
H = mass of nuts gathered by Harry
J = 12 + H
J = 3H
3H = 12 + H
3H - H = 12 + H - H
2H = 12
H = 6 kg
J = 18 kg
k, n - integers
2k+1 - an odd integer
2n+1 - another odd integer
The product of them:
(2k + 1)(2n + 1) =
= 4kn + 2k + 2n + 1 =
= 2(2kn + k + n) + 1
The product of integers (2kn) is integer
and the sum of them (2kn+k+n) also is integer
So (2k + 1)(2n + 1) = 2(2kn + k + n) + 1 is an odd integer
