Answer:
C) 5a + (2b + 3c)
Explanation:
According to the Associative Property of Addition, the grouping of numbers by parentheses in a different way does not affect their sum.
Therefore, 5a + (2b + 3c) is equivalent to (5a + 2b) + 3c because we are simply changing the way we group the terms, but not changing the overall sum of the terms.
