Answer 2

Answer:

Answer:

You'd pay $26.88

Step-by-step explanation:

So, you do 7.5%(25).

Then, you have 1.875, which rounds to 1.88

Next, you add 1.88 to 25.

Explain how you solve this: -7 = -1 + x/3

Answers

Answer:

-18 =x

Step-by-step explanation:

-7 = -1 + x/3

Add 1 to each side

-7+1 = -1+1 + x/3

-6 = x/3

Multiply each side by 3

-6*3 = x/3*3

-18 =x

Which polynomials are prime? Check all that apply.15x2 + 10x – 9x + 7
20x2 – 12x + 30x – 18
6x3 + 14x2 – 12x – 28

Answers

Prime polynomials are those polynomials that are not factored into lower degree polynomial. The options that are prime polynomials are 1), 4), and 5).

Evaluate all options in order to check that the polynomials are prime or not:

1). $15x^2 +10x -9x+7$

5x(3x + 2) - (9x - 7)

So, this polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.

2). $20x^2-12x+30x-18$

$4x(5x - 3)+6(5x-3)$

(4x + 6)(5x - 3)

So, this polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.

3). $6x^3+14x^2-12x-28$

$2x^2(3x+7)-4(3x+7)$

$(2x^2-4)(3x+7)$

So, this polynomial is converted into a lower degree polynomial. Therefore, it is not a prime polynomial.

4). $8x^3+20x^2+3x+12$

$4x^2(2x+5)+(3x+20)$

So, this polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.

5). $11x^4+4x^2-6x^2-16$

$x^2(11x^2+4)-2(3x^2+8)$

So, this polynomial can not be factored into lower degree polynomial. Therefore, it is a prime polynomial.

Answer:

The prime polynomials are 1, 4 and 5

Step-by-step explanation:

Given some polynomials we have to classify the polynomials prime or not.

Prime polynomials are the polynomial with integer coefficients that cannot be factored into lower degree polynomials.

$15x^2 + 10x - 9x + 7$

⇒ $5(3x+2)-(9x-7)$

can't be factored into lower degree polynomial ∴ prime polynomial.

$20x^2 - 12x + 30x - 18$

⇒ $4x(5x-3)+6(5x-3)$

⇒ $(4x+6)(5x-3)$

hence, not a prime polynomial.

$6x^3 + 14x^2 - 12x - 28$

⇒ $2x^2(3x+7)-4(3x+7)$

⇒ $(2x^2-4)(3x+7)$

hence, not a prime polynomial.

$8x^3 + 20x^2 + 3x + 12$

⇒ $4x^2(2x+5)+(3x+20)$

can't be factored into lower degree polynomial ∴ prime polynomial.

$11x^4 + 4x^2 - 6x^2 - 16$

⇒ $x^2(11x^2+4)-2(3x^2+8)$

can't be factored into lower degree polynomial ∴ prime polynomial.

The prime polynomials are 1, 4 and 5

Please help me ASAP. Many Thanks

you have to make the fraction into an integer. the simplest version of a ratio involves the smallest possible integers. therefore, 5:2.5 will equal 10:5 (you multiply both sides by 2). 10:5 cancels down to 2:1. hope this helped :)
