Answer 2

so many questions, so little time

Answer 3

\[\frac{2x^2+6x}{10x^3 }\\
=\frac{2x(x+3)}{2x\times 5x^2}\\
=\frac{\cancel{2x}(x+3)}{\cancel{2x}5x^2}\\
=\frac{x+3}{5x^2}\]

Answer 4

\[\frac{ x^2+6x+9}{5x+15 }=\frac{(x+3)(x+3)}{5(x+3)}=\frac{\cancel{x+3}(x+3)}{5(\cancel{x+3})}=\frac{x+3}{5}\]
