You can answer that for me

I just need a sec for it to load I know the communative property is 

 

The Commutative Property of Addition says that the order of the addends in a sum does not matter.

The Commutative Property of Multiplication says that the order of the factors in a product does not matter.

You can use the commutative properties to help you create an equivalent algebraic expression.

Rule

Commutative Property of Addition: a + b = b + a

Commutative Property of Multiplication: ab = ba

The commutative properties allow you to switch the order in a sum or product in an expression to suit your needs without changing the value of the expression. 

 

 

 

But the Problem is it is a real Problem not just with the letters so I dont know howyou would do a real one my lesson only taught Associtive Property....

You wrote this f:

 

Commutative Property of Multiplication:        ab = ba

 

So there has to be one thing multiplied by another thing.  Then the 2 are swapped around on the other side of the equal sign.

(Remember that a dot is a multiply sign)

 

So which one do you think is right?

OR which ones are you pretty sure are wrong ?

It is the fourth one Melody \

Because it is changing up the order alittle

I know the third is not correct 

 

the second is in correct 

\

And I belive the First is incorrect 

 

Is this Correct Melody?

The first one has 12a-6  on the right side.   This is not (one thing) X (another thing.)    So it is not right

 

the third one is not correct either.  Why??     

 

Which one is    first thing x second thingsecond thing x first thing              ??

Show me how you think the forth one works

 

left hand side is       (3*4a) - 2       What two things are multipled here.   

One thing is (3*4a)  the other thing is (2)   there is a minus sign between them.    NOT a times sign!

Don't over-think this , Nickolas!!!

 

Your  first answer  of "the second one" was correct......!!!!

 

Let  a  = 3

Let b  = ( 4a - 2)

 

So

3*(4a - 2) = (4a - 2)*3

a*b  = b*a

 

cool cool cool

The commutative property of multiplication says that a*b = b*a.

 

Because of this, the answer is the 2nd one.
