Answer:

6(n−2)

Step-by-step explanation:

Let be n ‘a number’

“difference of a number and 2” would be the result of that number minus two

Then n-2

“Six times” something would be the result of multipliying six by that

Then 6(n-2)

Find the area of the shaded regions.

Veronika [31]

Answer:

$A = A_c-A_t=4\pi -8=4.5664cm^2$

Step-by-step explanation:

The area of the shaded region can be calculated as the area of the semicircle less the area of the right triangle.

The area of the right triangle can be calculated as:

$A_t=\frac{b*h}{2} =\frac{LM*MN}{2}$

Where LM and MN have the same length because the internal angles are L=45°, M=90°, and N=45°. So the area is:

$A_t=\frac{4*4}{2}=8$

The diameter of the circle can be calculated using the Pythagorean theorem as:

$D=\sqrt{(LM)^2+(MN)^2} =\sqrt{4^2+4^4}=4\sqrt{2}$

So, the radius is $r=2\sqrt{2}$

Finally, the area of the semicircle is:

$A_c=\frac{\pi*r^2 }{2}=\frac{\pi*(2\sqrt{2})^2 }{2}=4\pi$

So, the area of the shaded region is:

$A = A_c-A_t=4\pi -8=4.5664cm^2$

Please help with this question

never [62]

Answer:

2,744 feet³

Step-by-step explanation:

Volume = Length * Width* Hight

A cube has all the sides equal in measure so Length and Width and Hight are equal and are given in the picture to be 14 feet.

V = 14 *14*14 = 2,744 cubic feet
