Answer:

Final answer is [tex](4x^2+3)(x+2)[/tex].

Step-by-step explanation:

Given expression is [tex]4x^3+8x^2+3x+6[/tex].

Now we need to factor that by the method of grouping.

So make two groups having first two terms and then last two term.

Factor each group then factor once more.

[tex]=4x^2(x+2)+3(x+2)[/tex]

[tex]=(4x^2+3)(x+2)[/tex]

It can't be factored anymore so the final answer is [tex](4x^2+3)(x+2)[/tex].

the factored form of 4x^3+8x^2+3x+6 using the grouping method is (x+2)(4x^2+3).

To factor the polynomial 4x^3+8x^2+3x+6 using the grouping method, we can start by grouping terms in pairs and factoring out common factors in each pair. Here is a step-by-step explanation:

Therefore, the factored form of 4x^3+8x^2+3x+6 using the grouping method is (x+2)(4x^2+3).

Answer: 12 feet.

Step-by-step explanation:

The formula used to calculated the area of a rectangle is:

[tex]A=l*w[/tex]

Where "l" is the lenght and "w" is the width.

You need to find the lenght of the bedroom, then you must solve for the lenght "l":

[tex]l=\frac{A}{w}[/tex]

You know that the floor of Paul's and Matthew's rectangular bedroom has an area of 132 square feet and its width is 11 feet. Then, you can substitute these values into [tex]l=\frac{A}{w}[/tex] to calculated the lenght. Therefore, the result is:

[tex]l=\frac{132ft^2}{11ft}[/tex]

[tex]l=12ft[/tex]

Answer:

The answer would be B, 2x2+7x-15.

Answer:

7

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [4, 6 ]

f(b) = f(6) = 6² - 3(6) - 10 = 36 - 18 - 10 = 8

f(a) = f(4) = 4² - 3(4) - 10 = 16 - 12 - 10 = - 6

Hence

average rate of change = [tex]\frac{8-(-6)}{6-4}[/tex] = [tex]\frac{14}{2}[/tex] = 7

Answer:

Step 3 is wrong.

Step-by-step explanation:

They must subtract the 28 from 15 first. This will give you 3x=-13. Then, you divide each side by 3, giving an answer of x=-4.33, or x=-13/3.

Answer:

step 3 is wrong

Step-by-step explanation:

consider step 2

3x + 28 = 15 ( subtract 28 from both sides ) gives

3x = 15 - 28

Answer:36 ft squared

Step-by-step explanation:

24 ft squared plus 12 ft squared equals 36 ft squared

20.00 for each pair of shoes

Cost of one pair of shoes is $4.0625 (Approx.)

Cost of 25 pair gloves and 15 pair shoes = $374.25

Cost of 14 pair gloves and 4 pair shoes = $117.49

Cost of one pair of shoes

Assume;

Cost of one pair of gloves = a

Cost of one pair of shoes = b

So,

25a + 15b = 374.25 ......... eq1

14a + 4b = 117.49 ......... eq2

eq2 × 3.75

52.5b + 15b = 440.5875 ........ eq3

Eq3 - eq1

a = 2.41

So,

14a + 4b = 117.49

b = $4.0625

Cost of one pair of shoes = $4.0625 (Approx.)

Answer:

x = 8

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

Answer: C 18000

Step-by-step explanation:

Julie contributes $12,000 to her 401k and her employer matches 50% of this amount, contributing an additional $6,000. Thus, the total balance in Julie's 401k after the employer's contribution is added is $18,000.

The question involves calculating the total balance in Julie's 401k account after her employer's contribution. Julie contributes $12,000 to her 401k, and her employer offers a 50% match on contributions. To find the total balance, first calculate the employer's contribution, which is 50% of Julie's contribution, so $12,000 x 0.5 = $6,000.

Adding the employer's contribution to Julie's contribution gives us the total balance in the 401k account. Therefore, $12,000 (Julie's contribution) + $6,000 (employer's match) = $18,000.

Answer:

24) C: {-9, -8, -7}

25) Add 6.1 to both sides of the equation.

Step-by-step explanation:

Question 24 is asking which set of numbers when subtracted by five is still greater than -15. C is the only one that matches.

(Edit: I realize after reading another answer that B is correct, not C. I misread the question.)

In question 25 you can easily solve for p by adding 6.1 to both sides of the equation.

Answer:

80°

Step-by-step explanation:

The opposite angles of an inscribed quadrilateral add up to 180.

(2x + 13) + (3x + 37) = 180

(2x + 3y) + (5y) = 180

Solving the first equation:

5x + 50 = 180

5x = 130

x = 26

Solving the second equation:

2x + 8y = 180

2(26) + 8y = 180

52 + 8y = 180

8y = 128

y = 16

5y = 80.  So ∠D = 80°.

Answer:

D

Step-by-step explanation:

Answer D is correct.  The indicated line segments are both radii of the circle and are thus of the same length (and thus, congruent).

Answer: D. RE

Step-by-step explanation:

In the given picture , we have a circle with center R having two chords as WF and MU.

The two chords WF and MU have equal length.

i.e. [tex]WF=MU=11.2[/tex]

We know that the equal chords of a circle are equidistant from the center.

⇒ [tex]\overline{RA}=\overline{RE}[/tex]

Therefore, we conclude that RA is congruent to RE.

Using the Pythagorean Theorem, you should get 45 [9 + 36]. Then, take the square root of 45 and simplify it to 3√5.
