Answer:
9.) B
10.) C
11.) ?
13.) B
14.) 25
15.) B
Step-by-step explanation:
9. The additive identity property says that if you add a real number to zero or add zero to a real number, then you get the same real number back. The number zero is known as the identity element, or the additive identity.
10. The identity element of multiplication, or the multiplicative identity element, is 1.
11. ?
13. Commutative property of addition:
Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+44, plus, 2, equals, 2, plus, 4.
14. For example, 25 is a perfect square because it is the product of integer 5 by itself, 5 × 5 = 25. However, 21 is not a perfect square number because it cannot be expressed as the product of two same integers.
15. The formula for the associative property of multiplication is (a × b) × c = a × (b × c). This formula tells us that no matter how the brackets are placed in a multiplication expression, the product of the numbers remains the same.
