(\frac{2}{5})^{2} + \frac{1}{2} - (\frac{1}{3} - \frac{3}{4}) + (- \frac{1}{2})^{2}

(\frac{2}{5})^{2} = \frac{4}{25}

- (\frac{1}{3} - \frac{3}{4}) = \frac{5}{12}

(- \frac{1}{2})^{2} = \frac{1}{4}

= \frac{4}{25} + \frac{1}{2} + \frac{5}{12} + \frac{1}{4}

\frac{4}{25} + \frac{1}{2} + \frac{5}{12} + \frac{1}{4} = \frac{199}{150}

= \frac{199}{150}

f = 2 (- 5)^{2} - 3 (- 5)

2 (x - 7) - 10 = 12 - 4 x

\frac{x}{9} + 6 < 4

1.8 \cdot 1 0^{- 5} = \frac{x ^{2}}{0.62}

- 9 (3 m - 6) = - 54
