You can find the perimeter by just counting the distance of every line segment all around the shape since they have vertical and horizontal slopes.
Answer:
The constant in the polynomial is 9. A constant number is a number that does not change during the equation. This equation is 4x² + 9. Since you are just adding 9 the number of 9 does not change. If you were multiplying 9 it would not be a constant anymore because it does not stay the same throughout the equation.

The answer you picked is correct.
X^2/3 = 64
![x^{2} =64^{3}](https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%3D64%5E%7B3%7D)
![x = 64^{3/2}](https://tex.z-dn.net/?f=x%20%3D%2064%5E%7B3%2F2%7D)
it is easier to first find square root of 64 and than power it to 3
square root of 64 is 8 which means our equation now looks like:
x = 8^3
now the answer is after powering 8 to 3:
x = 512
The answer would be 10 to the third because if you divide that it would equal 1,000
