The base would be x since it is being raised to the 2nd power in the expression. The base of an exponent is always the number being raised to a power or index.
There are 1000 mL in a Liter and 60 seconds in a minute
18 L / min = 18,000 mL /min
so in mL/s the answer is 18000 / 60 = 300 mL/s Answer
So in order for us to know which angle is the smallest and which one is the largest, take note that the largest angle is the opposite of the longest side, and the smallest angle is the opposite of the shortest side. So base on the given figure above, the smallest angle would be angle p, then next is angle q and the largest, therefore would be angle r. Hope this answer helps. So it is p,q,r.
Answer: C.

Step-by-step explanation:
