To determine

To state: the property of real numbers used in the given relation.

Expert Solution

Answer to Problem 14E

Distributiveproperty over addition of real numbers.

Explanation of Solution

Given information:

A relation is given as

  7(a+b+c)=7(a+b)+7c

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 7(a+b+c)=7(a+b)+7c , Distributive property over addition of real numbers has been used.
