Answer:
x = 5
Step-by-step explanation:
7x is a secant- secant angle and has measure equal to half the difference of the intercepted arcs, that is
7x = 0.5(22x + 10 - 50)
7x = 0.5(22x - 40) ← distribute
7x = 11x - 20 ( subtract 11x from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5
A because all of the numbers add up to 100 and there is 30 red so that would make it 30/100 and simplified it would be 3/10
The standard form is:

Degree = 5, leading coefficient=4
The 5th degree polynomial is:
Quintic function
it is a trinomial
<u>What is standard form of a polynomial?</u>
When expressing a polynomial in its standard form, the greatest degree of terms are written first, followed by the next degree, and so on.
So, standard form is:

To find the degree of the polynomial, add up the exponents of each term and select the highest sum ( if there are more than 1 variable in single term) or highest power of variable
Degree = 5
In a polynomial, the leading term is the term with the highest power of x.
So, leading coefficient=4
The 5th degree polynomial is:
Quintic function
It has 3 terms. so, it is a trinomial

Answer:
the answer is 9
Step-by-step explanation:
15/100 ?/60
multiply 60 by 15 to get 900, the divide 900 by 100 to get <em>9</em>
The first one because it’s (13(31)
