ANSWER

EXPLANATION
We want to find the cube root of

This is the same as:
![\sqrt[3]{216 {x}^{9} {y}^{16} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B216%20%7Bx%7D%5E%7B9%7D%20%20%7By%7D%5E%7B16%7D%20%7D%20)
We rewrite as radical exponent to get;

This implies that;

This simplifies to:

Hence the cube root is:

Line P, because it is the closest to the most data points

6.5
Step-by-step explanation:
To round 6.48 to nearest tenth means to round the numbers so you only have one digit in the fractional part.
Area of triangle = 1/2 x base x height
base = 15 + 6 = 21
height = 8
Area of triangle = 1/2 x 21 x 8 = 84 in²
