Question

1-28

Does anyone know or can someone help

I think it's B but I don't know for sure.
The Question:
What is the simplified form of the expression?
- 7m^2 + 6.5n - 4n + 2.5m^2 - n

A: 9.5m^2 + 1.5n
B: 4.5m^2 + 1.5n
C: 1.5m^2 - 4.2n
D: 9.5m^2 - 1.5n

Answer 1

If that leading - sign is correct, then none of the choices works, since you would have -4.5m^2
Otherwise, A is what you want
