VII)

$\frac{2(m - 7) \times (m + 7)}{n(n - 7)}$

Step-by-step explanation:

VI)

$\frac{{(x + 1)}^{2}}{6} \times \frac{2}{{x}^{2} - 1}$

$= \frac{2{(x - 1)}^{2} }{6(x - 1) \times (x + 1)}$

$= \frac{x - 1}{3(x+ 1)}$

VII)

$\frac{{m}^{2} - 49}{3n} \div \frac{2n - 14}{6}$

$= \frac{(m - 7) \times (m + 7)}{3n} \times \frac{6}{2(n - 7)}$

$= \frac{2(m - 7) \times (m + 7)}{n(n - 7)}$
