Question

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

Answer 1

*ignore the one point each for each correct property

Answer 2

will give a medal though

Answer 3

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

Answer 4

im not sure ? :/

Answer 5

really....? -_-

Distributive Property...

Answer 6

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

Answer 7

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`

Answer 8

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;

Answer 9

associative property ?

Answer 10

yayyyy

Answer 11

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..

Answer 12

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

Answer 13

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

Answer 14

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