The polynomial x^2 +3x+1 is a factor of x^3+2x^2-5x-6 Please select the best answer from the choices provided True
False

Answers

Answer 1
Answer:

A factor of a polynomial evenly divides the polynomial, without leaving a

remainder.

  • The statement, the polynomial x² + 3·x + 1 is a factor of x³ + 2·x² - 5·x - 6 is; False

Reasons:

By long division we have;

Given that (x³ + 2·x² - 5·x - 6) ÷ (x² + 3·x + 1) = (x - 1) remainder (-3·x - 5), we have;

(x² + 3·x + 1) is not a factor of (x³ + 2·x² - 5·x - 6) because it does not evenly divides (x³ + 2·x² - 5·x - 6)

Therefore, the polynomial, x² + 3·x + 1 is not a factor of x³ + 2·x² - 5·x - 6, the

statement is false

Answer 2
Answer: Answer: False

x^3+2x^2-5x-6 factors to (x-2)(x+1)(x+3)

None of the pair of factors multiply to x^2+3x+1

(x-2)(x+1) = x^2-x-2
(x-2)(x+3) = x^2+x-6
(x+1)(x+3) = x^2+4x+3

An item costs $4 before tax
and $4.32 after sales tax.
What is the sales tax rate?​

Answers

Answer:

The sales tax rate of an item that costs $4 is 8%

Step-by-step explanation:

An item costs $4 before tax

The same item costs $4.32 after sales tax.

So the tax rate can be calculated as:

Tax rate = $4.32 - $4 = $0.32

Next, you must divide the tax rate by the original price in order to get the sales tax rate:

Sales tax rate = $0.32/4$ = 0.08

In percentage:

Sales tax rate % = 0.08x100% = 8%

Answer:

costs $4 is 8%
