8f−15s−3

im just writing random things here because it wont let me answer without at least 20 characterssssssssss

Answer 2

8f-15s-3

Explanation:

Combine the like terms. 4f plus 16f is 20f. 20f minus 12f is 8f. There are no like terms for 15s so it stays. Finally, combine -20 and 17 and you get -3. So the answer is 8f - 15s - 3.
