Step-by-step explanation:

Height of the Cylinder= 30 feet

Diameter = 8 feet

Radius= Diameter/2 = 8/2 = 4 feet

The Amount of Metal Sheet used in constructing the tank is the Total Surface Area of the Tank.

Total Surface Area of a Cylinder =

Factor completely x^2-48

fredd [130]

Answer: $(x-7)(x+7)$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below;

- Make the equation equal to zero:

$x^{2}-49=0$

-Add 49 at both sides:

$x^{2}=49$

- Now, you must take the square root of both sides of the equation, then you obtain the following roots:

$x=\sqrt{49}\\x_1=7\\x_2=-7$

- Then you have:

$x^{2}-49=$ $(x-7)(x+7)$
