(b 7.2 + - 3.6 )
(c 7.2 + (-3.6)
(d 7.2 - - 3.6)

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
