Answer 1

Answer:the value of n(n+n)/n-1=8/9

Step-by-step explanation:if n=2/7then n(n+n)/n-1

2/7(2/7+2/7)/2/7+1

Answer 2

Step-by-step explanation:

$n = \frac{2}{7} \\ \\ \\ \\ \frac{n(n + n)}{n - 1} = \\ \\ = > \frac{n(2n)}{n - 1} \\ \\ = > \frac{ \frac{2}{7} (2 \times \frac{2}{7} )}{ \frac{2}{7} - 1} \\ \\ \\ = > \frac{ \frac{8}{49} }{ \frac{2 - 7}{7} } \\ \\ \\ = > > \frac{8}{49} \times \frac{7}{ - 5} \\ \\ \\ = > - \frac{8}{35} ans..$
