If you would like to solve the equation a^2 - 8*a + 12 = 0 for a, you can calculate this using the following steps:
a^2 - 8*a + 12 = 0
(a - 6) * (a - 2) = 0
1. a = 6
2. a = 2
The correct result would be B; 2, 6.

Answer:
The area of the pentagon is approximately 21 square units
Step-by-step explanation:
The radius of the circle in which the regular pentagon is inscribed, r = 3
The area of a pentagon, 'A', inscribed in a circle with radius, r is given as follows;
A = 5×(1/2) ×2×r·sin(32°)×r·cos(32°) = (5/2)×r²×sin(72°)
Therefore, the area of the pentagon, A = (5/2)×3²×sin(72°) ≈ 21.3987716166 ≈ 21
The area of the pentagon, A ≈ 21 square units.
