Answer 2

Let's break down the given expression step by step:

1. 17 - (-21.3): When you subtract a negative number from another number, it is the same as adding the positive value of that number. So, we have: 17 + 21.3 = 38.3

2. -(-3 - 2.8): The expression inside the inner brackets (-3 - 2.8) first needs to be calculated. Subtracting a negative number is equivalent to adding its positive value: -3 + (-2.8) = -5.8

Now, we have: -(-5.8)

To simplify the double negation, we can make it positive: -(-5.8) = 5.8

So the final result is: 5.8
