I think it will be right 17.3

Answer 2

Answer:

$8.7m^2 + 2m + 3.6$

Step-by-step explanation:

I am assuming that you mean:

$7.7m^2 + 5.5 + 7m -1.9 - 5m + m^2$

==================================

We will simplify the expression by combining like terms.

$7.7m^2 + 5.5 + 7m -1.9 - 5m + m^2\\\rule{160}{0.5}\\\\7.7m^2 + m^2 + 7m - 5m + 5.5 -1.9 \leftarrow \text{Rearrange the terms so all like terms are grouped together.} \\\\\boxed{8.7m^2 + 2m + 3.6}\leftarrow \text{Simplify}$

==================================

Hope this helps!
