If 2x^2+2x=12, what is x?

Rainbow [258]

Answer:

x= 2

x= -3

Step-by-step explanation:

Solving as normal quadratic equation:

2x^2+2x=12
x^2 +x = 6
x^2 + x - 6= 0
x = (-1 ± √(1+4*1*6)/2
x = ( - 1 ± √25)/2
x = (-1 ± 5)/2
x= 2
x= -3

Roots are 2 and -3

Find the volume of the cone.

8_murik_8 [283]

Answer:

$V=471\ \text{units}^3$

Step-by-step explanation:

Given that,

Radius of the cone, r = 5 units

Height of the cone, h = 6 units

We need to find the volume of the cone. The formula for the volume of the cone is given by :

$V=\pi r^2 h$

Substitute all the values,

$V=3.14\times 5^2\times 6\\\\V=471\ \text{units}^3$

So, the volume of the cone is $471\ \text{units}^3$ .
