It is unevenly distributed with the soil because over the year and states it changes around the country.
the options that are polynomials are:
3.9x³-4.1x² + 7.3
x²y²-4x³+12y
4-x²
<h3>Which algebraic expressions are polynomials?</h3>
A polynomial is an expression of the form:
p(x) = aₙ*xⁿ + ...+ a₂*x² + a₁*x + a₀
Where all the exponents of the variable are whole numbers, and in this case we have only one variable x, but we could have any number of variables.
With that in mind, the options that are polynomials are:
3.9x³-4.1x² + 7.3
x²y²-4x³+12y
4-x²
These 3 expressions are polynomials.

Answer:
The volume of the pyramid is not equal to the volume of the cylinder.
Step-by-step explanation:
A right cylinder has the circular cross-sectional area and if the cross-sectional areas of a right pyramid and a right cylinder are the same then the pyramid must be a right circular cone.
Now, the volume of a right cylinder is πr²h and that of a right circular cone is 1/3 πr²h.
Therefore, the radius of the base of the cone and that of the cylinder is the same and their heights are equal to be 5 units, then the volume of the pyramid is not equal to the volume of the cylinder. (Answer)
Answer & Step-by-step explanation:
So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857, which is the answer. To double check, you'd just find 14% of 2285.7142857 (multiply by 0.14) which is equal to 320. Because you can't have fractions of people, however, you'd have to round the answer up to 2286 people.
If that is too difficult to understand them hope this is easier
14% of the towns population is 320. Let P denote the towns population.
14/100 * P =320
14P/100 = 320
14P = 32000
divide both sides by 14
P = 2285.71
the towns population is 2286
Hope this helps!
