They're the same like integers.
First you should interpret it.
For example:
a. -3x + 8x is the same like -3 + 8. You just add x.
Which is 5x.
Answer: 9πcm²
Step-by-step explanation: area of the square= 36cm²
Therefore, the area of one side= √area = √36 = 6cms
Since the circle is touching the sides of the square, the side of the square = the diameter of the circle
Therefore the radius of the circle= side/2 = 3cm
The formula for the ares of the circle is πr²
π*3*3 = 9πcm²
The radius is 8

Answer: The correct answer is the second choice: "When any two polynomials are added, the result is always a polynomial."
When a set of numbers is "closed" under an operation, it means that the resulting output answer is the same type as the input.
For example, if you add 2x + 9 and 3x + 12, you get 5x + 21.
You started with 2 polynomials and you ended with a polynomial.
