Question

Select the postulate that is illustrated for the real numbers.

Answer 1

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.

Answer 2

Answer:

The distributive postulate.

Step-by-step 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.

$a(b+c)=a\times b+a\times c$

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

$3*x+3*1=3x+3$

Therefore, the correct choice is the distributive postulate.
