Dear student
Since you have not mentioned question number so doing as per my understanding.
$$\begin{gathered} 10. \\ \left(\frac{5\mathrm{x}+10}{\mathrm{x}+2}\right).\left(\frac{2\mathrm{x}}{4\mathrm{x}-10}\right) \\ =\left(\frac{5\cancel{\left(\mathrm{x}+2\right)}}{\cancel{\mathrm{x}+2}}\right).\left(\frac{\cancel{2}\mathrm{x}}{\cancel{2}\left(2\mathrm{x}-5\right)}\right) \\ =\frac{5\mathrm{x}}{2\mathrm{x}-5} \\ \mathrm{Note}: \\ \mathrm{a}\left(\mathrm{b}+\mathrm{c}\right)=\mathrm{ab}+\mathrm{ac} \end{gathered}$$
For remaining queries we request you to post them in separate threads to have rapid assistance from our experts.
