Answer:
1). x = 81
2). x = 84
Step-by-step explanation:
1). By applying geometric mean theorem in the given triangle,

56x = (18√14)²
56x = 4536
x = 
x = 81
2). By applying geometric mean theorem,

16x = (8√21)²
16x = 1344
x = 
x = 84
Step-by-step explanation:
Standard polynomial is:

Leading co effecient is:
-20
The answer is grade point average (GPA)
120 dollars minus the 35 dollar flat fee = 85 dollars. divide the 85 dollars by 20 to see how many hours they played. 85 divided by 20 = 4.25. they played 4 and 1/4 hours:)
