Question

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

Answer 1

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

Explanation:

=`(7s)/(s + 2) xx (2(s + 2))/21`

= `(cancel(7)(s))/(cancel(s + 2)) xx (2(cancel(s + 2)))/(cancel(21)_3)`

=`(s xx 2)/3`

= `(2s)/3`

Hopefully this helps!
