# How do you simplify (7s)/(s+2) times (2s+4)/(21)?

Mar 13, 2016

First , we must factor completely to see what we can eliminate before multiplying.

#### Explanation:

=$\frac{7 s}{s + 2} \times \frac{2 \left(s + 2\right)}{21}$

= $\frac{\cancel{7} \left(s\right)}{\cancel{s + 2}} \times \frac{2 \left(\cancel{s + 2}\right)}{{\cancel{21}}_{3}}$

=$\frac{s \times 2}{3}$

= $\frac{2 s}{3}$

Hopefully this helps!
