Factor completely x^2 - 4x - 12
Explain the steps.
^ = to the power of

Answers

Answer 1
Answer: Well x^2 is the same as x-squared (I don't know how to type it). 
So to start off, you have x-squared-4x-12 
Then you just have to combine the x's, and 1x-4x=-3x 
so your final answer would be -3x-squared-12

Every week, Hector works 20 hours and earns $210.00. He earns a constant amount of money per hour.Part A
Write an equation that can be used to determine the number of hours, h, Hector works given the number of weeks, W.
Enter your equation in the space provided

Part B
Write an equation that can be used to determine Hector's earnings, in dollars, m, for h hours of work.
Enter your equation in the space provided.

Answers

Answer:

A). h = 20 w

B). m = 10.5h

Step-by-step explanation:

Part (A).

Let the total number of hours Hector worked = h

And total number of weeks worked by Hector = w

Therefore, number of hours Hector worked in a week = (h)/(w)

Since, total number of hours worked in a week = 20

Equation will be,

20 = (h)/(w)

h = 20w

Part (B).

Per hour earning of Hector = \frac{\text{Total earning}}{\text{Number of hours worked}}=(210)/(20)

(m)/(h)=10.5

m = 10.5h

The volume of a cube is 1728 cubic units. what is the length of one side?

Answers

12 is the length of one side of cube.

What is cube?

In geometry, a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex. The cube is the only regular hexahedron and is one of the five Platonic solids. It has 6 faces, 12 edges, and 8 vertices

According to question, the volume of a cube is 1728 cubic units.

We have to find the length of the cube.

Volume=1728 cubic units

⇒lenght^(3) =12^(3)

⇒length =12units

Hence, 12 is the length of one side of cube.

L × W × H = 1728
L = W = H
I got 12 because 12 x 12 x 12 = 1728 I'm absolutely sure :)

There are many cylinders with a height of 9inches. Let r represent the radius in inches and v represent the volume in cubic inches what belongs in cell A

Answers

Complete question :

There are many cylinders with a height of 9 inches. Let r represent the radius in inches and V represent the volume in cubic inches.

a. Complete the table relating the radius and volume of cylinders with height 9 inches. Write each volume as a multiple of , or round to the nearest cubic inch.

Answer:

A = 9π in³

B = 36π in³

C = 81π in³

Step-by-step explanation:

Radius, r = 1, 2, 3

Height of cylinder = 9

Volume, V of cylinder : πr²h

For, r = 1

V = π(1)²9 = 9π in³

For, r = 2

V = π(2)²9 = 4*9π in³ = 36π in³

For r = 3

V = π(3)²9 = 9*9π in³ = 81π in³
