To find 3 times any number, Maria doubles the number and then adds the number again. a Show how Maria would solve \( 3 \times 6 \). \( \begin{array}{l}2 \times 6=12 \\ 12+6=18\end{array} \)

Select the correct answer. Solve the following equation. \[ \begin{array}{l}|x|+8=17 \\ \text { A. } x=9 \text { or } x=-9 \\ \text { B. } x=25 \text { or } x=-25 \\ \text { C. } x=25 \text { or } x=-9 \\ \text { D. } x=-25 \text { or } x=-9\end{array} \]

For the next set of problems, let \( \ln 2=a \) and \( \ln 3=b \). Use the properties of logarithms to write each logarithm in terms of \( a \) and \( b \). \( \begin{array}{ll}\text { 7) } \ln 6 & \text { 8) } \ln 8\end{array} \)

termine the area of the region bounded by \( x=-y^{2}+10 \) and \( =(y-2)^{2} \). etermine the area of the region bounded by \( x=y^{2} \) and \( x=12-2 y \) etermine the area of the region bounded by \( y=2 x^{2}+10, y=4 x+16 \), 3.3. Volumes \( x=5 \).

\( \begin{array}{ll}\text { a) } \frac{1}{5}=15 \\ \text { b) } \frac{1}{2 \times 2 \times 2}= & \text { d) } \frac{3 \times 3 \times 3 \times 3 \times 3}{3}= \\ \text { c) } \frac{1}{(-4) \times(-4) \times(-4) \times(-4)}= & \text { e) } \frac{1}{-6}= \\ \end{array} \)
