A: - 7 - 8n

B: - 7 + 8n

C: - 7 - 13n

D: - 7 - n (10.5 - 2.5)

E : - 7 + n (10.5 - 2.5

-3.5 (2-3n) - 2.5n simplifies to - 7+10.5n-2.5n, or - 7+8n. B is the correct answer.

Simplify step-by-step.

-3.5 (2-3n) - 2.5n

Distribute:

= (-3.5) (2) + (-3.5) (-3n) + - 2.5n

=-7+10.5n+-2.5n

Combine Like Terms:

=-7+10.5n+-2.5n

= (10.5n+-2.5n) + (-7)

=8n+-7

Which is same as option B).
