(x²+9)*(25(x²-4x+4))
x=±√-36/2, so x=±3i
x=4±√(16-16)/2, so x=2 is a double root
depends on how your teacher instructed you to county roots. there are 2 complex solutions and two real solutions because 2 is a double root. that would be D. however there are only 3 DISTINCT roots, , 3i, -3i, and 2 which would be C. The CORRECT answer to a mathematician would be D
F(x)=6x+57
F(18)=6x+57
F(18)=6(18)+57
F(18)=108+57
F(18)=165
Answer:
200π m²
Step-by-step explanation:
Lateral area of a cone = πrl
r = 8 m
l = 25 m
Plug in the values
Lateral area = π × 8 × 25
Lateral area = π × 200 = 200π m²
