Answer : x^7

When you’re multiplying variables like the one in the problem above, instead of actually multiplying, you add. You only multiply in cases where there are coefficients.

Example : z^4 * z^2

Instead of multiplying, you would add the exponents together like so, z^6.

Find the circumference and area of a circle with a diameter of 22 inches.
Katyanochek1 [597]

Answer:

  Circumference=22\pi\;inches \\\\Area =121\pi \;inches^2

Step-by-step explanation:

Diameter of the circle=22\;inches

Radius=\dfrac{22}{2} =11\;inches

Circumference of a circle:

            =2\times \pi \times r

            =2\times \pi \times 11\\\\=22\pi \;inches

Area of the circle:

                  =\pi \times r^2

                 =\pi \times 11\times 11\\\\=121\times \pi \\\\=121\pi \;inches^2

Guys, I really really need some help badly! I don't understand how to get the "GCF" aka greatest common factor. Can someone plea
Setler [38]

After I explain the procedure in full detail, you'll be able to generate
your own work.  Here it is.

To find the greatest common factor of two numbers:

1).  List all of the factors of the first number.

2).  List all of the factors of the second number.

3).  Scan both lists, and find factors that are on BOTH lists.
These are the COMMON factors.  Write them down in a short list.

4).  Scan the short list.  Find the biggest number on it.
That's the Greatest Common Factor.

OK, I'll go through the first one in your picture . . . 24  and  42 :

1). Factors of 24:  <em>1,  2,  3,</em>  4,<em>  6,</em>  8,  12,  24

2). Factors of 42:  <em>1,  2,  3,  6,</em>  7,  14,  21,  42

3). Short list:    <em>1, 2, 3, 6</em>

4). Biggest number on the short list:<em>  <u>6</u> </em>
