Question

The expression 7(b + c) is equivalent of 7b + 7c, uses the ________ property

  1. Commutative    
  2. Closure    
  3. Distributive    
  4. Identity    

Hint:

The given equation is an algebraic expression. An algebraic expression has a variable, a constant, and follows the operations of algebra. A variable is a quantity that doesn’t have a fixed value. A constant is a quantity with a fixed value. In this question, we are given an equation. We have to explain which law is used so that 7(b + c) can be written as 7b + 7c.

The correct answer is: Distributive


    The given equation is 7(b + c) = 7b + 7c.
    We can see that the 7 is distributed to b and 7.
    The quantity outside the bracket, or in other words, quantity in multiplication with bracket is equally distributed to the terms inside the bracket. This property is used in the above equation. And this property is distributive property
    So the right answer is distributive property.

    We should know the different properties used in algebraic operations.
