The answer is C that is X=7 and X=-1
multiple x through the given equation to get rid of a fraction. It will be
After that bring 6X to the LHS of the equation
so that it will look like the general equation that is
Use the quadratic formula (or any other approach to find the values of x
You will arrive at
For this case we have by definition, that the volume of a cone is given by:
Where:
A: It is the cone radius
h: It's the height
They tell us that the diameter is 21 m, then the radius is half the diameter, that is: 10.5m. The height is 4m. Substituting the data:
.
Finally, the volume of the cube is
