Multiplying each side by 42 (since 6*7=42), we get 7x+24x=3906=31x. Next, we can divide both sides by 31 to get 126

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,

Tim solved a subtraction problem. Write a number sentence to show the problem and answer. Tell how you got your answer. tim's an
Igoryamba

Answer:

<em>Problem with the subtraction is </em><em>950 - 863 = 87.</em>

Step-by-step explanation:

Now let us suppose Tim began at number 863 and finished at number 950. The numbers 7 + 30 + 50, or 87 were added.

He later discovered that 863 + 87= 950.

<em>Therefore the problem with the subtraction is 950 - 863 = 87.</em>
