<em><u>Solution:</u></em>
Polynomial is an expression with variables and coefficients,
Which involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables
<em><u>Option 1</u></em>
![4\sqrt[3]{x} -\sqrt{x} -20](https://tex.z-dn.net/?f=4%5Csqrt%5B3%5D%7Bx%7D%20-%5Csqrt%7Bx%7D%20%20-20)
Polynomial does not include roots
This is not a polynomial equation
<em><u>Option 2</u></em>
![x^4+3x^3-5x^2-7x+20](https://tex.z-dn.net/?f=x%5E4%2B3x%5E3-5x%5E2-7x%2B20)
This is polynomial expression involving addition and subtraction between terms with non-negative integer exponents of variables
<em><u>Option 3</u></em>
![\frac{5}{x^3}-\frac{1}{x^2}+\frac{8}{x}-40](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7Bx%5E3%7D-%5Cfrac%7B1%7D%7Bx%5E2%7D%2B%5Cfrac%7B8%7D%7Bx%7D-40)
This is not a polynomial. This equations involves negative integer exponents of variables

Hi!
//gm circumscribed by a circle must be a cyclic quadrilateral.
Answer: It is equal to the measure of angle C.
Step-by-step explanation:
If we know that Triangle ABC isosceles, then that means two sides and two angles are congruent to each other. Angle A must the topmost angle, and Angle B and C are probably the base angles. So, saying that, the base angles and sides are congruent to each other. Hence, Angle B must be equal to Angle C.
Answer:The value of the 1 in the ones place is 10 times the value of the 1 in the tenths place.
Step-by-step explanation:
Hello!
Let's divide our 48 students among groups of 3 students below.
48/3=16
Therefore, there are 16 debating teams.
I hope this helps!
