3 and -3 are said to be the square roots of 9. A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand. ... Negative numbers don't have real square roots since a square is either positive or 0.
Answer:
<h2>
4.5</h2>
Step-by-step explanation:
![x \times 2 + 1 = 10](https://tex.z-dn.net/?f=x%20%5Ctimes%202%20%2B%201%20%3D%2010)
![2x + 1 = 10](https://tex.z-dn.net/?f=2x%20%2B%20%201%20%3D%2010)
Move constant to R.H.S and change its sign
![2x = 10 - 1](https://tex.z-dn.net/?f=2x%20%3D%2010%20-%201)
Subtract the numbers
![2x = 9](https://tex.z-dn.net/?f=2x%20%3D%209)
Divide both sides of the equation by 2
![\frac{2x}{2} = \frac{9}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B2%7D%20)
Calculate
![x = 4.5](https://tex.z-dn.net/?f=x%20%3D%204.5)
Hope this helps..
Best regards!!
Answer: A
Step-by-step explanation:
The answer is a because the measure of angle KGH is 25 degrees since it is an inscribed angle. Angle GKJ is 130 degrees because angle GKL is 50 degrees. Therefore angle J is equal to 25 degrees which makes the triangle an isosceles triangle since angle J and angle KGH are equal to one another.
I am going to assume that the equation was supposed to be ![9y^{5}](https://tex.z-dn.net/?f=9y%5E%7B5%7D)
Answer:
It is a polynomial. It is a binomial and it has a degree of 5.
Step-by-step explanation:
A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables so ![9y^{5}](https://tex.z-dn.net/?f=9y%5E%7B5%7D)
will be considered a polynomial.
A binomial is a polynomial with 2 terms.
The degree of a polynomial is the highest exponent in it which in this equation is 5.
