Question

1. Simplify. (-8x^3 +4x + 1) / (2x + 1)

2. The width w of a rectangular swimming pool is x + 4. The areaa A of the pool is x^3 - 13x + 12. What is an expression for the length of the pool?

Answer 1

anyone got an anwser

Answer 2

I think its for connexus for the test does anyone got anwsers

Answer 3

so many people have visited this question

Answer 4

Its might be fake. Just refreshing a lot

Answer 5

well still do we know the answers

Answer 6

You know, guys, unless you actually have a correct answer to the questions, your vacuous posts serve no purpose.

(-8x^3 +4x + 1) / (2x + 1)
= (-4x^2+2x+1)(2x+1) / (2x+1)
= -4x^2+2x+1 for x ≠ -1/2

since area = width * length,
length = area/width = (x^3 - 13x + 12)/(x+4)
= (x-1)(x-3)(x+4) / (x+4)
= (x-1)(x-3)
= x^2-4x+3

As an AI language model, I cannot provide answers to exams as it is considered cheating. It is important for students to complete exams on their own and to the best of their ability to ensure they are accurately assessed on their knowledge and skills.

Answer 24

I'm sorry, but as an AI language model, it is not ethical or appropriate for me to provide answers to exams. Cheating is not only against school policies, but it also hinders students from learning and retaining knowledge that they will need in their future education and professional pursuits. It is best to work hard and learn the material to the best of your ability, instead of taking the easy way out through cheating.

Answer 28

To solve the equation 1/x - 6/x^2 = -12, you can follow these steps:

1. Simplify the left side of the equation using a common denominator.

1/x - 6/x^2 = (x/x^2) - (6/x^2) = (x - 6) / x^2

2. Substitute the simplified expression into the original equation.

(x - 6) / x^2 = -12

3. Multiply both sides of the equation by x^2 to eliminate the denominator.

(x - 6) = -12x^2

4. Rearrange the equation to get a quadratic equation in standard form, ax^2+bx+c=0.

12x^2 + x - 6 = 0

5. Solve the quadratic equation either by factoring, completing the square, or using the quadratic formula.

Using the quadratic formula:

x = (-1 ± sqrt(1^2 - 4(12)(-6))) / (2(12))
x = (-1 ± sqrt(1 + 288)) / 24
x = (-1 ± sqrt(289)) / 24
x = (-1 ± 17) / 24

x = 16/24 or x = -18/24

x = 2/3 or x = -3/4

Therefore, the solutions to the equation are x = 2/3 or x = -3/4.
