If your using pemdas the answer would be roughly 3.6 because you divide 8 and 3 first to get 2.6 repeated then do 2+2=4 then 4-3=1 + the original 2.6 = 3.6

The height of a cone is twice the radius of its base.

Crank

Answer:

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The volume of a cone is given by the formula

$V=\frac{1}{3}\pi r^{2}h$

we have

$h=2x\ units\\r=x\ units$

substitute

$V=\frac{1}{3}\pi x^{2}(2x)$

$V=\frac{2}{3}\pi x^{3}\ units^3$

6(8-x)(x+4)=0 what’s the solution set?

Travka [436]

Answer:

$x_{1} = -4\\\\x_{2} = 8$

Step-by-step explanation:

6(8-x)(x+4)=0

(48 -6x )(x+4) = 0

48x +192 -6x^2 -24x = 0

6x^2 -24x -192=0

using quadratic formula:

$x =\frac{-b+-\sqrt{b^{2}-4*a*c}}{2*a}$

a= 6 b= -24 c= -192

we have:

$x_{1} = -4\\\\x_{2} = 8$
