Well you see you take the sector and tie it 3 times the radiants which will then answer the question that you seek from within the depths of bones and minds.
Answer:
(c)
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos42° = 
= 
Multiply both sides by 12
12 × cos42° = x, hence
x ≈ 8.9 → (c)
X^2(x+4) x 3x^2(x-1)
(X^3+4x^2) x (3x^3 -3x^2)
3x^6 -3x^5+12x^5 -12x^4
3x^6 +9x^5-12x^4
I think that’s how you do it
The correct answer to this problem is D.
Answer:
x² + 2x + y² + 4y = 20
(x² + 2x + 1) - 1 + (y² + 4y + 4) - 4 = 20
(x + 2)² + (y + 4)² - 5 = 20
(x + 2)² + (y + 4)² = 25
Therefore, the center is (-2, -4) and the radius is √25 = 5.
