Answer:

2x² - 14x + 24

Step-by-step explanation:

Use the FOIL method (First, Outside, Inside, Last).

First, multiply the first term of both parenthesis:

2x * x = 2x²

Next, multiply the outside terms of both parenthesis:

2x * -4 = -8x

Then, multiply the inside terms of both parenthesis:

-6 * x = -6x

Finally, multiply the last terms of both parenthesis:

-6 * -4 = 24

Combine like terms:

2x² - 8x - 6x + 24

2x² (-8x - 6x) + 24

2x² (-14x) + 24

2x² - 14x + 24 is your answer.

Answer:

$2x^{2} -14x+24$

Step-by-step explanation:

1. Distribute

$(2x-6)(x-4)$

$2x(x-4)-6(x-4)$

2. Distribute

$2x(x-4)-6(x-4)$ Distribute $2x(x-4)$

$2x^2-8x-6(x-4)$

3. Distribute

$2x^2-8x-6(x-4)$ Distribute $-6(x-4)$

$2x^2-8x-6x+24$

4. Combine like terms

$2x^2-8x-6x+24$ Combine the like terms

$2x^2-14x+24$

HelloI need some assistance with this question. I provided an answer, but it was incorrect. The images are enclosed.

Given:

There are given that the zeroes and degrees of the polynomial:

$\begin{gathered} \text{zeros:}-2,2,4 \\ \text{Degres:}3 \end{gathered}$

Explanation:

From the concept of a polynomial:

A polynomial has a as zero if and only if (x -a) is a factor of the polynomial.

Then,

From the given polynomial:

$f(x)=(x+2)(x-2)(x-4)$

Then,

$\begin{gathered} f(x)=(x+2)(x-2)(x-4) \\ f(x)=(x^2-2x+2x-4)(x-4) \\ f(x)=(x^2-4)(x-4) \\ f(x)=x^3-4x^2-4x+16 \end{gathered}$

Final answer:

Hence, the polynomial is shown below:

$f(x)=x^3-4x^2-4x+16$

Alyssa is factoring the following expression p∆2-8p-9. She said the answer is (p-1) (p +9). Is she correct? If not, explain her

Lesechka [4]

Answer:

Step-by-step explanation:

p^2-8p-9

factor out the trinomial

(p-9)(p+1)

Therefore, she's incorrect. Because (p-1)(p+9)=p^2-p+9p-9=p^2+8p-9 and that's different from p^2-8p-9.

DENIUS [597]

<h3>Answer: 9 meters</h3>

===========================================

Work Shown:

side a = 8
side b = 5
angle C = 88 degrees

Applying the law of cosines

c^2 = a^2 + b^2 - 2*a*b*cos(C)

c^2 = 8^2 + 5^2 - 2*8*5*cos(88)

c^2 = 64 + 25 - 80*cos(88)

c^2 = 86.2080403

c = sqrt(86.2080403)

c = 9.2848285

c = 9

Technically he needs 10 meters of rope because of the extra 0.28 portion, but I'll stick with 9 meters since your teacher said to round to the nearest whole number.

10. If 1000 cm = 1 l, find the capacity of the following water tank in litre

Lelu [443]

<h2>Given :</h2>

length = 200 cm

breadth = 150 cm

height = 100 cm

<h2>Solution : </h2>

$\large \boxed{volume = l \times b \times h}$

$200 \times 150 \times 100$

$3000000 \: \: cm {}^{3}$

Through the statement above we have,

$\small\mathrm{1000 \: cm³ = 1 \: \: }l$

$\small\mathrm{1 \: cm {}^{3} = \dfrac{1}{1000} \: }l$

$\small\mathrm{3000000 \: cm {}^{3} = 3000000 \times \dfrac{1}{1000} \: }l$

$\small\mathrm{3000000 \: cm {}^{3} = 3000000 \times \dfrac{1}{1000} \: }l$

$\small\mathrm{ 3000 \: \: litres}$
