Answer:
51
Step-by-step explanation:
Given
P(x) = 2x³ + 4x² - 10x - 9, then
P(a) = 2a³ + 4a² - 10a - 9 ← substitute x = a into P(x)
To evaluate P(3) substitute a = 3 into P(a)
P(3) = 2(3)³ + 4(3)² - 10(3) - 9 = 54 + 36 - 30 - 9 = 51
Since P(3) ≠ 0 then (x + 3) is not a factor of P(x)
Recall the double angle identity for cosine:

It follows that

Since 0° < 22° < 90°, we know that sin(22°) must be positive, so csc(22°) is also positive. Let x = 22°; then the closest answer would be C,

but the problem is that none of these claims are true; cot(32°) ≠ 4/3, cos(44°) ≠ 5/13, and csc(22°) ≠ √13/2...
