Choose two axioms that allow 6 + (x + 5) to be written x + 11.
A) commutative - addition
B) distributive
C) associative - multiplication
D) symmetric
E) commutative - multiplication
F) associative - addition
G) identity - addition

Respuesta :

associative means that you can move the parenthesis around the problem and still get the same answer. like (4+2)+3=4+(2+3)
first & sixth are the true

Basic number properties:

  • The Distributive Property: [tex]a\cdot (b+c)=a\cdot b+a\cdot c;[/tex]
  • The Associative Property for addition: [tex]a+(b+c)=(a+b)+c;[/tex]
  • The Associative Property for multiplication: [tex]a\cdot (b\cdot c)=(a\cdot b)\cdot c;[/tex]
  • The Commutative Property for addition: [tex]a+b=b+a;[/tex]
  • The Commutative Property for multiplication: [tex]a\cdot b=b\cdot a;[/tex]
  • Identity Property : Any number add to the zero the answer is the number itself;
  • The symmetric property states that if one number is equal to a second number, then the second number is equal to the first number.

For the expression 6 + (x + 5):

  1. use The Commutative Property for addition - 6+(x+5)=(x+5)+6;
  2. use The Associative Property for addition - (x+5)+6=x+(5+6)=x+11.
