2267 Faktorisera genom att bryta ut en gemensam faktor. \( \begin{array}{ll}\text { a) } 6 x+14 & \text { c) } 25-5 y \\ \text { b) } 3 x-9 & \text { d) } 2-10 y\end{array} \)

2 varies directly as the cube of \( x \) and inversely as \( y \). If \( z=237 \) when \( x=10 \) and \( y=2 \), find \( z \) if \( x=8 \) and Round your answer to two decimal places if necessary.

\( 2 x - \frac { 16 x + 1 } { 5 ^ { x + 1 } } + 1 = 0 \)
