Answer:

The method of separation is chromatography.

Step-by-step explanation:

It is given that a drawing of a circle made in the center of a piece of paper with a black marker gets wet, the marker bleeds, and as the water moves through the paper the ink separates into several colors. Here, the method of  separation used is chromatography. It is a laboratory technique for the separation of a mixture. When water or dye passes through a medium and changes color, then that means chromatography is used there.

Factor the polynomial completely using the X method. X2 13x – 48 An x-method chart shows the product a c at the top of x and b a
Ratling [72]

X method is the method to find the factors of the polynomial equation.The factor of the given polynomial is,

x^2+16x-3x-48=(x+16)(x-3)

Thus the option 3 is the correct option,

<h3>How to find factor of polynomial using X method?</h3>

X method is the method to find the factors of the polynomial equation.

The standard form of the quadratic equitation is given as,

ax^2+bx+c

Given information-

The equation given in the problem is,

x^2+13x-48

Compare the above equation with the standard form. We get,

a=1\\b=13\\c=-48

To find out the factor of above equation using X method, follow the steps.

  • Step 1) Multiply a and c and place ac at the top of X as shown in the image.

        ac=1\times(-48)\\ac=-48

  • Step 2) Place b at the bottom as shown in the image below.

       b=13

  • Step 3) Find two numbers that multiply the top number ac and to the bottom number b.

  • Step 4) Write the polynomial from the X box as,

         x^2+16x-3x-48=x(x+16)-3(x+16)

         x^2+16x-3x-48=(x+16)(x-3)

Hence the factor of the given polynomial is,

x^2+16x-3x-48=(x+16)(x-3)

Thus the option 3 is the correct option,

Hello!

If there is only one repeating digit, you will put it out of 9. This gives us 2/9.

Therefore, our fractions is \boxed {\frac{2}{9}}.

I hope this helps!
