8 - sqrt(3) is indeed the conjugate of 8 + sqrt(3).
What are you asking here? You are to "evaluate or simplify" what?
18 i think that’s what it would be
Answer: You will need to know that the volume of a cone can be calculated using the formula V = 1/3*Pi*r^2*h, where V is the volume, r is the radius and h is the height. Next substitute the radius and volume into the formula. After this divide the volume by 1/3, r^2 and Pi to give the height of the cone.
H = V(3) / R^2(Pie)
Hey there :)
f (x) = 5x² - 2x
g (x) = 3x² + x - 4
( f + g )( x ) is f ( x ) + g ( x )
5x² - 2x + 3x² + x - 4
Combine like-terms
5x² + 3x² - 2x + x - 4
8x² - x - 4
Your option will be the third option
