9514 1404 393

  (i) commutative property of addition

  (ii) associative property of addition

  (iii) additive inverse property of addition

  (iv) identity element property of addition

  (v) multiplicative inverse property of multiplication

Step-by-step explanation:

(i) The commutative property lets you swap the positions of terms in a sum

(ii) The associative property lets you reposition parentheses in a sum

(iii) The additive inverse property tells you the sum of a value and its additive inverse is zero

(iv) The identity element property tells you adding 0 does not change the value

(v) The multiplicative inverse property tells you the product of a value and its multiplicative inverse is 1

the infinity sign

step-by-step explanation:

14 ft 7 inches

step-by-step explanation:
