Which of the following best describes the relationship between (x-3) and the polynomial x^3+4x^2+2?
Anna71 [15]
This is the concept of polynomials, to get the relationship between the (x-3) and (x^3+4x^2+2) we shall proceed as follows;
we first test if (x-3) is a polynomial;
x-3=0
thus;
x=3
substituting the value of x in the polynomial we get:
(3)^3+4(3)^2+2
=65
since the result is not equal to 0, we conclude that there is no relationship between (x-3) and the polynomial. The answer is B. (X-3) is not a factor

Solve for v.<br><br> 14 − 10v + 11 = 20v + 5(–7v − 11)<br><br> v =
AlexFokin [52]

Answer:

v = -16

Step-by-step explanation:

<u>→Distribute the 5 to (-7v - 11):</u>

14 - 10v + 11 = 20v - 35v - 55

<u>→Add like terms:</u>

25 - 10v = -15v - 55

<u>→Add 15v to both sides:</u>

25 + 5v = -55

<u>→Subtract 25 from both sides:</u>

5v = -80

<u>→Divide both sides by 5:</u>

v = -16

Jackson wants to purchase a home theater system that sells for $2500. Either he can pay the total amount at the time of purchase
N76 [4]

Answer:

$90

Step-by-step explanation:

To find out how much money he can save by paying the total amount at the time of purchase, first you have to determine the total amount that Jackson would pay if he can agree to pay $250 down and $130 a month for 18 months:

$250+(130*18)=$2590

Then, you need to find the difference:

$2590-$2500=$90

According to this, the answer is that you will save $90 by paying the total amount at the time of purchase.
