<h3>Your answer would be C, or 3x(x^{2} -4x+9).</h3>

To factor this polynomial, take out a greatest common factor from all of the terms.

In this case, we can look at the coefficients of x and x itself separately, and then combine them at the end.

The coefficients of x are 3, -12, and 27.

The greatest common factor between these numbers would be 3, as each of those numbers are divisible by 3.

Now, looking at x, you see x^{3}, x^{2}, x.

The greatest common factor between these numbers would just be x, as all of these are divisible by x.

Now, combine these factors. 3 and x are the two greatest common factors, and putting them together, you get 3x.

To finish factoring this, factor out 3x from the polynomial, and combine them.

The polynomial is 3x^{3}-12x^{2} +27x. To factor 3x out of them, divide each term by 3x.

3x((3x^{3} / 3x) - (12x^{2} / 3x) + (27x / 3x))

3x(x^{2}  - 4x + 9)

That would be your answer, C.

Good luck!

Answer:

3x³-12x²+27x

3x( x² - 4x + 9)

So simply , (c) is the answer

What is the rule? 100 cm 1 m, 250 cm ? M, 1500 cm ? M
kirza4 [7]
There are 100 cm(centimeters) in a m(meter).
So, to solve this, we divide 250 by 100. this gives us 2.5meters.
1500÷100=15meters
The rule is m=cm÷100.

If y = 8 cm, what is the area of the blue section of this shape?
Ivahew [28]

Answer:

56 cm squared

Step-by-step explanation:

First things first: Cop one triangle off the rectangle, and attach it to the other one, so the shape looks like a L

Now I can actually solve this:

The left side is 8 cm (because y = 8 cm)

The top is 10 cm

The middle is 6 cm

The inside left is 3 cm

And the very bottom is 2 cm

First, we'll solve for the newly constructed rectangle: 3 x 2. That equals 6.

Next, solve for the longer rectangle: 10 x 5. That's 50.

Now, add the two areas, and we get 56. So the area of the whole thing is 56 cm squared.

(Please keep in mind that I could be wrong, so double check it for me, thanks!)

Use the definition of a derivative to find f’(x).
tatyana61 [14]

Answer:

f'(x) = -\frac{9}{x^2}

Step-by-step explanation:

i) f(x) = 9 / x

ii) f'(x)  = $\lim_{h\to 0} \frac{f(x+h) - f(x)}{h} $  \hspace{0.2cm}

        = $\lim_{h\to 0} \frac{\frac{9}{x+h}  - \frac{9}{x} }{h}  =  \hspace{0.1cm} $\lim_{h\to 0} \frac{9x - 9(x+h)}{hx(x+h)} $ \hspace{0.1cm} =  \hspace{0.1cm}$\lim_{h\to 0} \frac{-9h}{hx(x+h)}  =  $\lim_{h\to 0} \frac{-h}{x(x+h)} = \frac{-9}{x^2}$
