Question

please give me the answer fast????

please solve this question fast who will give me first I will make him brainleast answer and rate also 5 stars.​

Answer 1

1.a. (-16) commutative property

b. 0. additive identity

c. (-7) associative property

d. -(18+4) distributive property

2. a. -12+4= -8

4-12= -8

a+b=b+a

b. a+(b+c)= -12+(4-25)

= -12-21= -33

(a+b)+c= (-12+4)-25

= -8-25= -33

c. not a whole number

d. a-b= -12-4= -16

b-a=4-12= -8

no here it's unequal

Answer 2

Answer:

Q1

a) -16 [Commutativity]

b) 0 [Additive identity]

c) (-7) [Associativity]

d) -22 [Distributivity]

Q2 [Put in the values, I am giving direct answers]

a) -8= -8

b) -33= -33

c) No, B and C are not closed under subtraction because the answer is not in whole number.

d) -16 ≠ -8

here's the direct answer, just know about properties of arithmetic operations

$closure \: property \:( x + y) \: (x - y) \: (x \times y) \: (x \div y)$

Commutative Property:- x+y = y+x, x * y = y *x [Division and subtraction is not equal]

Associative Property:- x+(y+z) = (x+y)+z, x*(y*z)= (x*y)*z[Division and subtraction is not equal]

Distributive property over addition [not applicable for subtraction] x*(y+z) = x*y + x+z
