Answer:
The correct answer is distributive postulate.
Step-by-step explanation:
Look at the expression we have given:
3x + 3 = 3(x + 1)
And we are asked that which postulate is illustrated for the real numbers.
We know that the distributive 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
where a,b and c are real numbers.
3(x+1)= 3*x+3*1 = 3x+3
Therefore the correct option is distributive postulate....
