Answer:

The answer to your question is given below.

Step-by-step explanation:

To which of the above expression is a sum or difference of cube, or not a sum or difference of cube, we shall do the following simplification:

Note: The Cube root of a particular number is simply a multiplication of an identical number in three places.

64x³ – 216

64 has a cube root of 4 and 216 has a cube root of 6. Therefore, the above expression can be written as:

4³x³ – 6³

(4x)³ – 6³

64x³ – 216 = (4x)³ – 6³

Therefore, 64x³ – 216 can be expressed as a difference of cube.

8x^9 + 27

8 has a cube root of 2, x^9 has a cube root of x³ and 27 has a

cube root of 3. Therefore, the above expression can be written as:

2³(x³)³ + 3³

(2x³)³ + 3³

8x^9 + 27 = (2x³)³ + 3³

8x^9 + 27 can be expreessed as a sum of cube

x³ + 125

125 has a cube root of 5. Therefore, the above expression can be written as:

x³ + 5³

x³ + 125 = x³ + 5³

x³ + 125 can be expressed as a sum of cube

36x³ + 121

36 and 121 has no cube root. Therefore, the above expression is not a sum or difference of cube.

x^6 – 16

x^6 has a cube root of x² and 16 has no cube root. Therefore, the above expression is not a sum or difference of cube.

Summary:

Sum or Difference of cubes

64x³ – 216

8x^9 + 27

x³ + 125

Not a Sum or Difference of cubes

36x³ + 121

x^6 – 16

I believe it is -8 since the point where the line is x=80 and y=-10. Then you divide x/y (80/-10) and get -8.

Max builds rail fences. For one one style of fence, each section use 3 vertical fence post and 6 horizontal rails. How many rail
Gekata [30.6K]

Answer: For a fence that has 18 posts he needs 36 rails.

Step-by-step explanation:

Hi, to answer this question we have to use proportions:

Each section use 3 vertical fence post and 6 horizontal rails

The proportion is = 3 post /6 rails

For 18 posts:

18 posts / x rails.

3 /6 = 18 /x

Solving for x:

x = 18 / (3/6)

x = 36 rails

For a fence that has 18 posts he needs 36 rails.

Feel free to ask for more if needed or if you did not understand something.
