Step-by-step explanation:

#The generalized from of 39 is

If we expand a number. 39 is two digit number.

It has ones place and tens place.

Ones place  = 9

Tens place  = 3

Tens place number represents by 10×3

So, 39 = 10×3 + 9

#Addition of 15m - 5m' and 6m' - 13m

Add two algebraic expression with variable m and m'

⇒ 15m - 5m' + 6m' - 13m

write like term together

⇒ 15m - 13m - 5m' + 6m'

combine the like term
