D) us Americans as men or women really don't get that much recondition. therfore if they can reach it easily, why would the get represented. imagine like the willy wonka and the charlie factory they only had 5 tickets in the whole world. if the whole world had them it wouldn't be as exselirating.

If CD=18, find the value of EB.
aliina [53]

Step-by-step explanation:

Chord AB and Chord CD are equidistant from the center of the circle.

\therefore \: chord \: AB \cong chord \:  CD \\  \\  \therefore \:  \frac{1}{2} \:  \: AB \cong \frac{1}{2} \: \:  CD  \\  \\ \therefore \: EB = \frac{1}{2} \:  \times 18\\  \\  \huge \purple{ \boxed{\therefore \: EB =9}}

Find the greatest common factor of the following monomials: 20a3 and 8a2
dimulka [17.4K]

GCF of given monomials are 4a^2

<em><u>Solution:</u></em>

<em><u>Given that we have to find the greatest common factor</u></em>

Given monomials are:

20a^3 \text{ and } 8a^2

When we find all the factors of two or more numbers, and some factors are the same, then the largest of those common factors is the Greatest Common Factor

Let us first find the GCF of 20 and 8 and then find GCF of variables and then multiply them together

<em><u>GCF of 20 and 8:</u></em>

The factors of 8 are: 1, 2, 4, 8

The factors of 20 are: 1, 2, 4, 5, 10, 20

Then the greatest common factor is 4

GCF\ of\ a^3 \text{ and } a^2\\\\a^3 = a^2 \times a\\\\a^2 = a^2

Thus GCF is a^2

<em><u>Therefore GCF of monomials are:</u></em>

\text{GCF of } 20a^3 \text{ and } 8a^2 = 4 \times a^2 = 4a^2

Thus GCF of given monomials are 4a^2
