Answer: A) 3(2k+4h).
Explanation: To answer this question we need to know one of the basic properties of mathematical operations, that is the commutative property of addition, which states that changing the order of addends does not change the sum, this means that if we add 5+3 or 3+5 they both will equal 8. In the given operation, if we multiply 3(4h+2k) it would be the same to calculate 3(2k+4h) because 2k+4h is the same as 4h+2k.
