Answer:
174 feet below sea level
Step-by-step explanation:
y is the number of minutes so you can multiply 14 by 9
14*9 is 126
then you add 126 to -300
126 + (-300) is essentially 126 - 300 and that is -174
the submarine was at 174 feet below sea level
If you multiply 8.5 by 50 cents your answer will be 4.25
25 + 100i is correct because -5 squared is 25 and the the square root of -100 is 100i or 10i in its simplest form.
