Distributiveproperty over addition of real numbers.

Explanation of Solution

Given information:

A relation is given as

  2(A+B)=2A+2B

Calculation:

Distributiveproperty over addition of real numbers:

Suppose a, b, and c are three real numbers, Distributive property says that

  a(b+c)=ab+ac

Product of a number with a sum can be changed to sum of products.

Therefore, in 2(A+B)=2A+2B , Distributive property over addition of real numbers has been used.
