Answer:
only (2) and (4) are polynomial out of given options.
Step-by-step explanation:
Polynomial is an expression having variables having positive integer exponents with real constant coefficients. example 
We are given some polynomials and we have to choose whether are polynomial or not.
Consider ,
1) 
Since, Polynomial does not have a fractional exponent.
So, 1) Not a polynomial.
2) 
Since all of the variables have integer exponents that are positive this is a polynomial.
3) 
Not a polynomial because a term has a negative exponent
.
4) 
Since all of the variables have integer exponents that are positive this is a polynomial.
Thus, only (2) and (4) are polynomial out of given options.
I think its false i read allot of that kind of stuff
Answer: a = 18
Step-by-step explanation:
The pythagorean theorem says that the sum of the square of the two legs of a triangle is equal to the square of the hypotenuse.
The two legs are 80 and a, and the hypotenuse is 82 which gives us
80² + a² = 82²
a² = 324
a = 18.
Answer:
Step-by-step explanation:
<u>Area of rectangle:</u>
= Length * Width
Where length = 4, Width = 6
= 4 * 6
= 24 cm²
<u>Area of semi-circle:</u>
Diameter = 6 cm
Radius = D/2 = 6/2 = 3 cm
Area = πr² / 2
Area = (3.14)(3)²/2
Area = (3.14)(9) / 2
Area = 28.3 / 2
Area = 14.1 cm²
<u>Area of the whole figure:</u>
= Area of the rectangle + Area of the semi-circle
= 24 + 14.1
= 38.1 cm²

You don’t need a mixed number because 4 1/2 - 1 2/4 = 3. It’s the same as 4 1/2 - 1 1/2
