Answer:
54 - 3n²
Step-by-step explanation:
Square of a number n = n²
Three times the square of n = 3*n² = 3n²
Expression:
54 - 3n²
One possible way:
-86+(4*12)=-38
-86 is the number where the diver is. 86 feet below the surface.
4*12 is the total number of feet he has ascended in 12 minutes.
Because he is ascending, so you add 4*12 (or 48) to -86.
The answer is -38, meaning he's 38 feet below the surface.
The diver is now 38 feet below the surface.
Hope this helps.
