Answer:
B and C
Step-by-step explanation:
7.2 - 3.6 is the original equation
B states that 7.2 + -3.6 is equivalent, and it is right because and positive and negative multiplied by each other gives a negative
C states that 7.2 + (-3.6) is equivalent, and it is also correct because it would still be a negative number because its subtracting
A and D would just add up so it wouldn't be equivalent to 7.2 - 3.6
