Answer: The completely factored form will be

3x^2(4x+1)(x+3)

Step-by-step explanation:

Since we have given that

12x^4 + 39x^3 + 9x^2

We need to find the factored form,

So, here we go:

1) Taking out the common factor i.e. 3x² :

12x^4 + 39x^3 + 9x^2\\\\3x^2(4x^2+13x+3)

2) We get a quadratic equation , we will split the middle term:

(4x^2+13x+3)\\\\4x^2+12x+x+3=0\\\\4x(x+3)+1(x+3)=0\\\\(4x+1)(x+3)=0

3) Now, combine the all of the factors:

3x^2(4x+1)(x+3)

Hence, the completely factored form will be

3x^2(4x+1)(x+3)

Hello,

12x^4+39x^3+9x²=x²(12x²+39x+9)=x²(12x²+36x+3x+9)=x²(4x(3x+9)+(3x+9))
=x²(3x+9)(4x+1)
=3x²(x+3)(4x+1)

PLEASE HELP! A juice company gives prizes to anyone finding specially marked caps on its juice bottles. You and your friends buy
laiz [17]

The odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.

<h3>What is odds against?</h3>

In probability, the term odds against is the ratio of probability of non occurring a favorable event to the probability of occurring a favorable event. It can be given as,

\text{odd against}=\dfrac{P(\overline A)}{P(A)}

Here, P(\overline A) is the probability of not occurring a favorable event, and P(A) is the probability of occurring a favorable event.

A juice company gives the prizes to anyone finding specially marked caps on its juice bottles. The 4 bottles have winning cap in 20 bottles. Thus, the probability of winning is,

P(A)=\dfrac{4}{20}\\P(A)=\dfrac{1}{5}

The probability of not winning is,

P(\overline A)=1-\dfrac{1}{5}\\P=\dfrac{4}{5}

Thus, the odd against the winning is,

\text{odd against}=\dfrac{\dfrac{4}{5}}{\dfrac{1}{4}}\\\text{odd against}=\dfrac{16}{5}\\\text{odd against}=3.2

Thus, the odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.

Give the equation of the horizontal asymptote shown below.
Oxana [17]
Polynomial division yields

\dfrac{7x^2}{x^2+5}=7-\dfrac{35}{x^2+5}

As x\to\pm\infty, you have the remainder term approaching 0, so the horizontal asymptote is the line y=7.

Clarissa got a part time job during the first week she earned $439.50. During the second and third week she worked a total of 62
iren2701 [21]

Answer:

$2063.44

Step-by-step explanation:

1st week = $439.50

2nd and 3rd week = 62 hours and each hour = $22.79

Total amount earned in 2nd and 3rd week = 62 * 22.79 = $1412.98

4th week = 48% of what she earned in her first week = 48% of $439.50

4th week = (48 / 100) * 439.50 = $210.96

Total amount she earned = 1st week + 2nd & 3rd week + 4th week

Total amount = $439.50 + $1412.98 + $210.96

Total amount = $2063.44

She earned a total of $2063.44
