14. Find the inverse of the matrix \( A=\left[\begin{array}{ll}2 & 5 \\ 1 & 3\end{array}\right] \). \( \begin{array}{ll}\text { a. }\left[\begin{array}{cc}-3 & -5 \\ -1 & 2\end{array}\right] \\ \text { b. }\left[\begin{array}{cc}3 & 5 \\ -1 & 2\end{array}\right] & \text { c. }\left[\begin{array}{cc}2 & -1 \\ -5 & 3\end{array}\right]\end{array} \)

Multiply. \[ (x+6)\left(x^{3}-2 x+5\right) \] \( (x+6)\left(x^{3}-2 x+5\right)=\square \)

17. \( 9 \frac{1}{12}=\frac{x}{9} \), Find \( X \)

10. Tenglamani yechishdan oldin uning chap va o'ng tomonlarini soddalashtirib oling. \( 548+t+278=178 \cdot 406-558182: 397 \)

Multiply. \[ (x+5)(x+6) \] \( (x+5)(x+6)=\square \) (Simplify your answer.)

Multiply. \[ \frac{1}{2} x^{2}\left(8 x^{2}-4 x+1\right) \] \( \frac{1}{2} x^{2}\left(8 x^{2}-4 x+1\right)=\square \) (Simplify your answer. Use integers or fractions for any numbers in the expression.)
