Real numbers are simply the combination of Whole numbers, Integers, Rational and Irrational numbers in the number system.

02

Step-2 – Distributive Property of Multiplication 

Suppose a, b, and c is three real numbers.

Distributive Property of Multiplication

Property: a(b+c)=a·b+a·c

Example: 12(3+4)=12·3+12·4=36+48=84

03

Step-3:  Evaluate the expression using the distributive property. 

Distributive Property of Multiplication

Property: a(b+c)=a·b+a·c

3  (y+9)=  3  ·  y  +  3  ·  9  =  3y  +  273  (y+9)=  3y+  27
