Answer:
15-12s or -12s+15 (usually we put variables infront of constants bc it more formal, you dont have to tho)
Step-by-step explanation:
Answer: 15-12s
Because the number (-3) is in front of the bracket that means that you have to times everything inside by it.
So,
-3×-5=15
-3×4s=-12s
So the answer would be 15-12s
Hope this helps :)
