Answer:
B, E
Step-by-step explanation:
Given expression
[tex]-2.5(1-2n)-1.5n[/tex]
First, use the distributive property:
[tex]-2.5(1-2n)-1.5n\\ \\=-2.5\cdot 1-2.5\cdot (-2n)-1.5n\\ \\=-2.5+5n-1.5n[/tex]
Use distributive property once more:
[tex]-2.5+5n-1.5n\\ \\=-2.5+n(5-1.5)[/tex]
So, option E is correct.
Now,
[tex]-2.5+n(5-1.5)\\ \\=-2.5+n\cdot 3.5\\ \\=-2.5+3.5n[/tex]
Thus, option B is correct
