Let's evaluate the expression step by step:

$$ \frac{4.8}{-2} + (4 + 5)^2 $$

1. **Divide 4.8 by -2:**
   
   $$
   \frac{4.8}{-2} = -2.4
   $$

2. **Calculate the sum inside the parentheses:**
   
   $$
   4 + 5 = 9
   $$

3. **Square the result:**
   
   $$
   9^2 = 81
   $$

4. **Add the two results together:**
   
   $$
   -2.4 + 81 = 78.6
   $$

**Final Answer:** $$78.6$$
The final answer is 78.6.
