Simplify the fraction by reducing it to its lowest terms.

(3) \( P(3 ; 0), \quad r: 2 x-\frac{3}{2} y-2=0 \)

Considerando - ¿Es el conju - ¿S genera al B. \( \boldsymbol{S}=\{(1,2,3 \)

4. Substitua o valor de \( a=2 \) e \( b=-3 \) nas expressões algé- bricas, a seguir. \( \begin{array}{ll}\text { a) } \frac{2 a+b}{2} & \text { c) } \frac{2 a^{2}+b^{3}}{b-a} \\ \text { b) }-\frac{3 a-2 b}{a b} & \text { d) } \frac{-(a-b)^{3}}{\frac{1}{2}(3 a b)} \\ \text { 5. Substitua e calcule o valor numérico dos binôminos, } \\ \text { a seguir, para } x=2 . & \text { c) }-\frac{1}{2} x^{4}+x^{2} \\ \text { a) }-2 x^{2}+x & \text { d) } x^{3}-x \\ \text { b) }-3 x^{3}-2 x & \end{array} \)

\( \frac{25}{30}=\sqrt{3} \) (Simplify your answer.)

Rotate the given triangle \( 180^{\circ} \) counter-clockwise about the origin. \( \left[\begin{array}{ccc}0 & -3 & 5 \\ 0 & 1 & 2\end{array}\right] \) \( \left[\begin{array}{lll}0 & {[?]} & {[ } \\ 0 & {[ } & {[ }\end{array}\right] \)
