Distributive Property

First take care of whatever is in parenthesis then add the like terms.

For example 6(d-5) +25

First multiply what is outside of the parenthesis 6(d) - 6(5) + 25

6d - 30 + 25 Combine what is the same. We have -30+25=-5

The answer would be 6d -5 because you combined the constants -30 and 25.

For example 9 + 3(2s + 7)

First multiply 3(2s+7)= 6s+21

Then put it together with the 9+ 6s+7

Commutative Property 9+7+6s=(9+7)+6s

16+6s or you can also say it is 6s+16

Then you multiply the number outside the parenthesis with each coefficient inside. For example: 3(2x + 3y +z) = 3(2x) + 3(3y) + 3(z)=

6x + 9y + 3z this is the answer because there are no like terms.
