The graph represents the relation y = x^o2 - 3x - 3. Find the value of x for which x² - 3x = 7

Simplify \(\frac{m}{n} + \frac{(m - 1)}{5n} = \frac{(m - 2)}{10n}\) where n \(\neq\) 0

G varies directly as the square of H, If G is 4 when H is 3, find H when G = 100

Given that n(p) = 19, m(P \(\cup\) Q) = 38 and n(P \(\cap\) Q) = 7, Find n(C)
