Question

Select the postulate that is illustrated for the real numbers.

3x + 3 = 3(x + 1)


The commutative postulate for multiplication
Multiplication by one
The addition inverse postulate
Commutative postulate for addition
The distributive postulate
The addition of zero postulate
The multiplication inverse

Answer 1

The distributive postulate.

Explanation:

We have been given an equation
`3x+3=3(x+1)`. We are asked to select the postulate that illustrated for the real numbers.

We know that distribute property of multiplication states that we can multiply a sum of numbers by multiplying each addend separately and finally add the products.

`a(b+c)=a* b+a* c`

After distributing 3 over
`(x+1)` we will get,

`3*x+3*1=3x+3`

Therefore, the correct choice is the distributive postulate.

Answer 2

I think the correct answer from the choices listed above is the distributive postulate. The expression 3x + 3 = 3(x + 1) is an example of a distributive postulate. It says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately. Hope this answers the question.
