## JennWoww 2 years ago help please ! will give a medal to the first person Tell the property used in each of the steps. One point each for each correct property. Steps Property 3 + 4(x + 1) Given = 3 + (4x + 4) A = (4x + 4) + 3 B = 4x + (4 + 3) C = 4x + 7 D

*ignore the one point each for each correct property

2. JennWoww

will give a medal though

So in step $$\large A$$ the 4 was distributed to each term inside the brackets. Can you think of what property that might be? :) Distributing hmmmmmmm

4. JennWoww

im not sure ? :/

5. zepdrix

really....? -_- Distributive Property...

6. JennWoww

ohhh hahaha i feel dumb lol i was thinking of that but i wasnt sure if it had something else or not

Step B is a little trickier. They rearranged the order of the addition. You can do this based on the fact that addition can happen in any order you want. $$\large 2+3+5 \qquad = \qquad 5+2+3$$ The numbers can commute ... Blah I can't think of a better way to say that lol It's the Commutative Property

Step $$\large C$$, the 4 is now associating with the 3 instead of the 4x. Can you think of what property this might be? c;

9. JennWoww

associative property ?

10. zepdrix

yayyyy

11. zepdrix

I'm not sure what property that is in part $$\large D$$. It's just addition being performed. I think it's called the Additive Identity Property. I better look that up to be sure though..

12. zepdrix

No that's not right, that property involves adding 0 to something.

13. zepdrix

Yah I dunno, maybe it's just the Addition property or something :\

its ok ill just put that :) thank you for everything :)
