4) A + b = b +a is an example of which mathematical property?

Commutative Property (Order Property)

Associative Property (Grouping Property)

Distributive Property

The given equation, a + b = b + a, demonstrates the commutative property of addition. This property states that the order of adding two numbers does not affect the sum. In other words, when adding two numbers, it doesn't matter which number comes first, the result will remain the same.

Explanation

The given equation, a + b = b + a, demonstrates the commutative property of addition. This property states that the order of adding two numbers does not affect the sum. In other words, when adding two numbers, it doesn't matter which number comes first, the result will remain the same.

5) A + (b +c) = (a + b) + c is an example of which mathematical property?

Commutative Property (Order Property)

Associative Property (Grouping Property)

Distributive Property

The given equation, a + (b + c) = (a + b) + c, demonstrates the Associative Property (Grouping Property) in mathematics. This property states that the grouping of numbers being added or multiplied does not affect the result. In this case, regardless of whether we first add b and c or a and b, the final sum will be the same. The equation shows that the addition of b and c is grouped together and then added to a, which is equivalent to adding a and b first and then adding c.

Explanation

The given equation, a + (b + c) = (a + b) + c, demonstrates the Associative Property (Grouping Property) in mathematics. This property states that the grouping of numbers being added or multiplied does not affect the result. In this case, regardless of whether we first add b and c or a and b, the final sum will be the same. The equation shows that the addition of b and c is grouped together and then added to a, which is equivalent to adding a and b first and then adding c.

6) A x (b + c) = (a x b) + (a x c) is an example of which mathematical property?

Commutative Property (Order Property)

Associative Property (Grouping Property)

Distributive Property

The given equation, a x (b + c) = (a x b) + (a x c), represents the Distributive Property. This property states that when multiplying a number by the sum of two other numbers, you can distribute the multiplication to each term inside the parentheses. In this case, the multiplication of a by the sum (b + c) is equal to the sum of the multiplication of a by b and the multiplication of a by c.

Explanation

The given equation, a x (b + c) = (a x b) + (a x c), represents the Distributive Property. This property states that when multiplying a number by the sum of two other numbers, you can distribute the multiplication to each term inside the parentheses. In this case, the multiplication of a by the sum (b + c) is equal to the sum of the multiplication of a by b and the multiplication of a by c.

7) What is the prime factorization of 120?

2 x 2 x 2 x3 x 5

10 x 12

2 x 2 x 5 x 6

The prime factorization of a number involves finding the prime numbers that multiply together to give the original number. In this case, the prime factorization of 120 is 2 x 2 x 2 x 3 x 5. This means that 2, 3, and 5 are the prime numbers that, when multiplied together, equal 120.

Explanation

The prime factorization of a number involves finding the prime numbers that multiply together to give the original number. In this case, the prime factorization of 120 is 2 x 2 x 2 x 3 x 5. This means that 2, 3, and 5 are the prime numbers that, when multiplied together, equal 120.
