Collect like terms \[ 3 c+13 c-7 c \]

2.) \( -\frac{\frac{5}{12}}{\frac{2}{3}}= \)

If \( h(x)=(x+10)^{2} \), find functions \( f(x) \) and \( g(x) \) so that \( h(x)=f(g(x)) \), \( f(x)= \) \( g(x)= \)

\( A = \left[ \begin{array} { c c c } { 1 } & { 3 } & { - 1 } \\ { 2 } & { 0 } & { 4 } \\ { 1 } & { 2 } & { 5 } \end{array} \right] \quad B = \left[ \begin{array} { l l l } { 3 } & { 2 } & { 1 } \\ { 4 } & { 0 } & { 1 } \\ { 0 } & { 1 } & { 1 } \end{array} \right] \)

Find a simplified expression for \( \tan \left(\sin ^{-1}\left(\frac{b}{10}\right)\right) \) \( \square \)

1) \( 91=-7(2-3 r) \)
