Question

Choose two axioms that allow 6 + (x + 5) to be written x + 11.

Answer 1

Answer:

commutative - addition

associative - addition

Step-by-step explanation:

commutative is when you can move them in any order and associative can be added in any order.

So you move (x+5) to look like (x+5)+6        (commutative)

then  switch parenthesis :  x+(5+6)            (associative)

then x+11.

Answer 2

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
