Answer:
C and D
Explanation:
First lets solve each equation by order of operations.
The first pair is (3+6)/2 and 3+(6/2).
The expressions solve to 4.5 and 6. 4.5 is NOT equal to 6.
Then you continue solving the expressions.
The next set of expression equals to 24 and 14, which are NOT equal.
The set after that solves to 4 and 4. Since they are equal the expressions are equal.
Finally the last set equals 36 and 36 which are equal.
