Answer 1

Second option.

Explanation:

`-17.9-4.2=17.9+(-4.2)`

Answer 2

Answer: Second option

Step-by-step explanation: In this problem, we are given the expression -17.9 - 4.2 and we are asked to rewrite the same problem but express it in a way that uses addition. Remember that when you are subtracting a positive number, it’s the same thing as adding a negative number so -17.9 - 4.2 can be rewritten as -17.9 + (-4.2.)
