<h2><em><u>EXPLANATION :-</u></em></h2>

= (2 {n}^{2} - 5n - 6) + (  - {n}^{2} - 3n  + 11)

= 2 {n}^{2}  - 5n - 6 -  {n}^{2} - 3n  + 11

= 2 {n}^{2} -  {n}^{2}  - 5n - 3n - 6 + 11

= (n²-8n+5)→Answer

I hope that it answer your question...

In the Volume of Cylinders, Cones and Spheres section, what is the volume of a sphere with a radius of 6in? *
Rudiy27

Answer:

The volume of the sphere is 288π in³

Step-by-step explanation:

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius

V = ⁴⁄₃πr³

V = ⁴⁄₃ * π * (6in)³

V = π * ⁴⁄₃ * 216 in³

V = 288π in³

The volume of the sphere is 288π in³

9. What is the slope of the line through the points (-2, -1) and (4, 3)?
Fofino [41]

Step-by-step explanation:

given points,

(-2, -1) and (4,3)

we know,

slope of line = y_2 - y_1/ x_2 - x_1

x_1 and y_1 = -2 , -1

x_2 and y_2 = 4 , 3

according to the formula

3 - (-1)/4 - (-2)

→ 3 + 1/4 + 2

→ 4/6

→ 2/3

or (2,3)

therefore, slope of the given line is (2,3).

Hope this answer helps you dear!
