Hello from MrBillDoesMath!
Answer: C)
Discussion:
To solve x^2 = 36/81 take the square root of both sides.
x = square root of (36/81)
As 36 = 6*6 and 81 = 9*9,
x = square root of (6*6)/ (9.9) or 6/9
But 6 and 9 share the common factor "3" so
x = 6/9 = (2*3)/(3*3) = 2/3
The last equality was gotten by cancelling the common factor 3.

Answer:
The geometric mean of 14 and 20 is 16.73.
Step-by-step explanation:
It is required to find the geometric mean of 14 and 20. Let the numbers are :
a = 14 and b = 20
The geometric mean for two numbers is given by :

Plugging the values in above formula as follows :

So, the geometric mean of 14 and 20 is 16.73.
3 x 2 = 6

Answer:
G is smaller than P. Visually comparing G to P you are doing a rough comparison to a 90° (or right) angle. Angle G is a little bit tilted to the right making it just under 90°
