Mathematics
1 answer:
FinnZ [79.3K]3 years ago
4 0

Answer:

1.5n

Step-by-step explanation:

The distributive property can be used to simplify expressions like this (collect terms).

= n(4 -1 +.5 -2)

= n(3 +.5 -2)

= n(3.5 -2)

= n(1.5)

= 1.5n

_____

Of course, you can do the addition in any convenient way. Some like to add all the positive and negative terms, then find the difference.

= n((4 +.5) -(1 +2)) = n(4.5 -3) = 1.5n
