Which property is illustrated by the statement?
The answer is B) Commutative Property of Multiplication .
What property is illustrated by multiplication?
| PROPERTIES OF MULTIPLICATION | Identity Property There is a unique real number 1 such that for every real number a , a⋅1=a and 1⋅a=a One is called the identity element of multiplication. | Multiplicative Property of −1 For all real numbers a and b , a(−1)=−a and (−1)a=−a |

What does reflexive property look like?
Defining the Reflexive Property of Equality
You are seeing an image of yourself . You could look at the reflexive property of equality as when a number looks across an equal sign and sees a mirror image of itself! Reflexive pretty much means something relating to itself.
What property is 9×7 7×9?
right triangle, distributive property , commutative property.
What are the 3 properties of multiplication?
Explore the commutative, associative, and identity properties of multiplication. In this article, we’ll learn the three main properties of multiplication.
How do you use distributive property to multiply?
- Simplify the numbers. In this example, 101 = 100 + 1, so: ...
- Split the problem into two easier problems. Take the number outside the parentheses, and multiply it by each number inside the parentheses, one at a time. ...
- Add the products.
Which equation shows the distributive property of multiplication?
The distributive property of multiplication states that a ( b + c ) = a b + a c . It’s often used for equations when the terms within the parentheses can’t be simplified because they contain one or more variables.
What’s the difference between reflexive and symmetric property?
The Reflexive Property states that for every real number x , x=x . The Symmetric Property states that for all real numbers x and y , if x=y , then y=x .
How do you prove reflexive property?
| Statements Reasons | 2. a c = a c ac=ac ac=ac 1. Reflexive property of equality |

What property is 3 x x 3?
So, the expression “three times the variable x” can be written in a number of ways: 3x, 3(x), or 3 · x. Use the distributive property to expand the expression 9(4 + x).
What is commutative property addition?
The commutative property of addition says that changing the order of addends does not change the sum . Here’s an example: 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+4.
Which property is illustrated if ∠ a ≅ ∠ B then?
| PROPERTIES OF CONGRUENCE | Reflexive Property For all angles A , ∠A≅∠A . An angle is congruent to itself. These three properties define an equivalence relation | Symmetric Property For any angles A and B , if ∠A≅∠B , then ∠B≅∠A . Order of congruence does not matter. |

What are the 3 properties?
- Commutative Property.
- Associative Property.
- Identity Property.
- Distributive Property.
What is an example of the distributive property?
When we are required to multiply a respective number by a sum of two numbers in such a case the distributive property of multiplication over addition is applied. For example, let us multiply 7 by the sum of 20 + 3. ... The multiplication of 7(20) and 7(3) will be performed before the addition.
