-2.8

Explanation:

{(3-sqrt9)-(-8-0.4)}/-3

sqrt9=3 so (3-sqrt9)=(3-3)=0

{0-(-8-0.4)}/-3

two negative signs cancel out to give a positive number

{8+0.4)/-3

{8.4)/-3

It's generally good to not have negative numbers in the denominator.

- {8.4)/3

This fraction can be expressed in decimal form.

- {8.4)/3=-2.8
