1) \( { }^{x}-2 \cdot x+1=0 \)

12. Evaluate \( f(x)=-x-2 \) for the following: a) \( \mathrm{f}(8) \) b) \( \mathrm{f}(-3) \) c) \( \mathrm{f}(5) \)

Формула для вычисления объёма пирамиды \( V=\frac{1}{3} S h \), \( S- \) площадь основания, \( h \) - высота пирамиды. Найди высоту, если \( V=115, S=30 \).

If \( \alpha \) and \( \beta \) are the zeroes of the polynomial \( x^{2}-7 x+3 \), then the value of \( \frac{\alpha^{4}+49 \alpha^{2}-14 \alpha^{3}-19}{\beta^{3}-7 \beta^{2}+\alpha^{2}-10 \alpha} \) is
