which expression is equivalent to −12+(−45)+31 and includes the correct justification for the equivalence?


a
−12+(−45)+1555 by the additive inverse property
b
−12+31+(−45) by the commutative property
c
(−45)+(−12)+31 by the associative property
d
−12+31+(−0.8) because the opposite of a sum is the sum of its opposites.
