Find:

we have to simplify the given expression.

Explanation:

we will simplify the given expression as following

1.7m² + 6.5n - 4n+ 2.5m² – n = (1.7 + 2.5)m² + (6.5 - 4 - 1)n = 4.2m² + 1.5n

Therefore, we get

1.7m² +6.5n - 4n+ 2.5m² – n = 4.2m² + 1.5n

Therefore, correct option is 4.2m² + 1.5n.
