\[\boxed{\mathbf{155}.}\]
\[1)\ (x + 5)(x + 2) > 0\]
\[Ответ:x < - 5;x > - 2.\]
\[2)\ (x + 1)(x - 4) \leq 0\]
\[Ответ:\lbrack - 1;4\rbrack.\]
\[3)\ \frac{x - 7}{x + 8} \leq 0\]
\[Ответ:( - 8;7\rbrack.\]
\[4)\ \frac{x + 6}{x - 10} \geq 0\]
\[Ответ:x \leq - 6;x > 10.\]
\[5)\ (x - 1)x(x + 3) \leq 0\]
\[(x + 3)x(x - 1) \leq 0\]
\[Ответ:x \leq - 3;\ \ 0 \leq x \leq 1.\]
\[6)\ x(x + 2)(x - 3) > 0\]
\[(x + 2)x(x - 3) > 0\]
\[Ответ:\ - 2 < x < 0;x > 3.\]
\[7)\ \frac{2x^{2} - x}{x + 1} > 0\]
\[\frac{2x(x - 0,5)}{x + 1} > 0\]
\[Ответ:\ - 1 < x < 0;\ \ x > 0,5.\]
\[8)\ \frac{3x^{2} + x}{x - 2} \leq 0\]
\[\frac{3x\left( x + \frac{1}{3} \right)}{x - 2} \leq 0\ \]
\[Ответ:x \leq - \frac{1}{3};\ \ 0 \leq x < 2.\]
