Answer:
-[b + 2.3]
or
-b - 2.3
Step-by-step explanation:
I'm assuming this is a multiple choice question but since you didn't list the choices I will just simplify the equation and hope for the best.
The negatives sign in front of the brackets is multiplying that quantity by -1, so first we distribute the negative to everything in the brackets.
14.8 - 4b - 17.1 + 3b
Combine like-terms
-b - 2.3
