50.24. I used the formula for area of a circle and that’s what I got.
I think it’s C but I’m not too sure
Answer:
a) - 9/2 or -0,45
b) - 3/5 or -0,6
c) -4
d) 1
e) -2
d) 0
Step-by-step explanation:
If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.
So,
1.



are polynomials.
2.

y
2 + s

are all polynomials.
3.
If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.
Hence,
is a cubic trinomial.
4.
The highest power is the degree.
Hence, degree of the polynomial is 2 + 4 = 6.
