Answer: Choice C

Explanation:

We can verify the answer by distributing the -3 through to each term inside

-3 times 1.5n = -4.5n
-3 times -1 = 3

This shows that -3(1.5n-1) is the same as -4.5n+3. The process of factoring out the GCF like this is basically the reverse of the distributive property.

The distributive property in general is [tex]a(b+c) = ab+ac[/tex]
