Answer 2

To simplify the given expressions, let's combine like terms:

12a + 20b + 18a + 45b = (12a + 18a) + (20b + 45b) = 30a + 65b

16c + 24d + 28c + 63d = (16c + 28c) + (24d + 63d) = 44c + 87d

30m + 42n + 49m + 21n + 15m + 25n = (30m + 49m + 15m) + (42n + 21n + 25n) = 94m + 88n

48x + 60y + 15m + 25n = 48x + 60y + 15m + 25n (no simplification possible since the terms are not like terms)

Therefore, the simplified expressions are:

30a + 65b, 44c + 87d, 94m + 88n, and 48x + 60y + 15m + 25n.
