The correct answer are:    "40 – 2" and "17 + 21".


Solution:

To identify the correct option, we check all the given options.

20 + 8 = 28

40 – 2 = 38

42 + 6 = 48

17 + 21 = 38

We observe that, out of all the options, 40 – 2 and 17 + 21 are the options that make the number 38.

So, 40 – 2 and 17 + 21 are the correct options.
