Answer: Choice C
Explanation:
We can verify the answer by distributing the -3 through to each term inside
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]
