The Students' Conjectures Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Polynomial product B: (x2 + x – 2)(4x2 – 8x)

Answers

Complete Question:

Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Polynomial product B: (x2 + x – 2)(4x2 – 8x) They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.

Answer:

[tex]A = B[/tex]

Step-by-step explanation:

See comment for complete question

Given

[tex]A: (4x^2 - 4x)(x^2 - 4)[/tex]

[tex]B: (x^2 + x - 2)(4x^2 - 8x)[/tex]

Required

Determine how they can show if the products are the same or not

To do this, we simply factorize each polynomial

For, Polynomial A: We have:

[tex]A: (4x^2 - 4x)(x^2 - 4)[/tex]

Factor out 4x

[tex]A: 4x(x - 1)(x^2 - 4)[/tex]

Apply difference of two squares on x^2 - 4

[tex]A: 4x(x - 1)(x - 2)(x+2)[/tex]

For, Polynomial B: We have:

[tex]B: (x^2 + x - 2)(4x^2 - 8x)[/tex]

Expand x^2 + x - 2

[tex]B:(x^2 + 2x - x - 2)(4x^2- 8x)[/tex]

Factorize:

[tex]B:(x(x + 2) -1(x + 2))(4x^2- 8x)[/tex]

Factor out x + 2

[tex]B:(x -1) (x + 2)(4x^2- 8x)[/tex]

Factor out 4x

[tex]B:(x -1) (x + 2)4x(x- 2)[/tex]

Rearrange

[tex]B: 4x(x - 1)(x - 2)(x+2)[/tex]

The simplified expressions are:

[tex]A: 4x(x - 1)(x - 2)(x+2)[/tex] and  

[tex]B: 4x(x - 1)(x - 2)(x+2)[/tex]

Hence, both polynomials are equal

[tex]A = B[/tex]

What number should be added to both sides of the equation to complete the square?

x^2-10x=12​

Add 5² to both sides:

x²-10x+5² = 12+5²

Answer:

  900 grams

Step-by-step explanation:

The equation tells you the initial amount of A is 700 grams.

The table tells you B is being cut in half each hour, so the amount when h=0 is 2×800 = 1600 grams.

The difference in the initial amounts is ...

What is the greatest number of items that could have been placed on each​ plate? Wellness Sale Donations Celery 63 Cucumbers 14 Carrots 35 The greatest number of items that each plate could have is nothing items. ​(Type a whole​ number.)

Answers

Answer:

The greatest number of items on each plate is 7

Step-by-step explanation:

Given

[tex]Celery = 63[/tex]

[tex]Cucumber = 14[/tex]

[tex]Carrot = 35[/tex]

Required

Determine the greatest number of items on each plate

To do this, we simply calculate the GCF of 63, 14 and 35

[tex]63 =3 * 3 * 7[/tex]

[tex]14 = 2 * 7[/tex]

[tex]35 = 5* 7[/tex]

The GCF is:

[tex]GCF = 7[/tex]

Hence:

The greatest number of items on each plate is 7

Answer:

The function's behavior close to the vertical asymptote, x = 2 is;

[tex]\lim\limits_{x \to 2^-} f(x) = \infty[/tex] and [tex]\lim\limits_{x \to 2^+} f(x) = -\infty[/tex]

Step-by-step explanation:

From the graph of the function. we have;

1) As 'x' approaches 2 from the left (x → 2⁻), the graph with 'u' shape located in the middle of the three graphs, approaches infinity (arrow pointing up)

2) As 'x' approaches 2 from the right (x → 2⁺), the graph with 'n' shape located at the right side of the three graphs, approaches negative infinity (-∞) (arrow pointing down)

Therefore, the function's behavior close to the vertical asymptote, x = 2 is given as follows;

[tex]\lim\limits_{x \to 2^-} f(x) = \infty[/tex] and [tex]\lim\limits_{x \to 2^+} f(x) = -\infty[/tex]

how do you simplify 1 1/8 x 3 2/3 someone please help me!

Answers

Answer:

4 1/8

Step-by-step explanation:

1 1/8 x 3 2/3 = ?

9/8 x 11/3 = 99/24

99/24 = 4 1/8

Answer:

1. find the least common denominator for the left-hand side fraction. This brings you to 8/8x + 3x/8x = 1/2

2. Add the numerator on the left-hand side of this equation, (8+3x)/8x = 1/2

3. Multiply both sides by 2, that will lead you to (8+3x)/4x =1/1

4. Multiply both sides by 4x, we get 8+3x=4x

5. Finally, subtracting 3x from both sides simplifies the equation to x=8. Note that this is as simple as this expression can get so you can not go any further, therefore 1/x+3/8=1/2 simplifies to x=8.

Responsible farming practices help minimize harm to the Great Barrier Reef. It is important that fertilizers and pesticides are used properly. Equally important is using less of them and only when necessary. It is also important for farmers to learn how to properly manage and avoid soil erosion. The Queensland Farmers' Federation is an organization of 2,600 farmers who have land along the Great Barrier Reef. They have joined together to work towards better land management practices. This sort of action is vital to the ongoing protection of the Great Barrier Reef.Passage 2Tourism brings in several billions of dollars each year, and over 60,000 people are employed by the Great Barrier Reef Marine Park. The protection of the reef is in the best interest of both the environment and the local economy. Among the many environmental threats to the reef, there are stories of hope. Scientists recently explored a mysterious blue hole in the Great Barrier Reef. The massive, underwater hole is located over 200 kilometers from Daydream Island in one of the least-explored areas of the reef. A team of marine biologists dove over 65 feet into the blue hole.
