8 0

1st, 2nd,& 4th. If the variable is in the root or in the denominator / have a negative power, then it is not a polynomial. The 3rd one has the root of y, so it isnt a polynomial.

Can anyone help me please, I need to figure out the value of n with work shown

Dmitry [639]

Answer:

n = 15

Step-by-step explanation:

This is a right triangle, and so the Pythagorean Theorem applies:

x^2 + 8^2 = 17^2

Solving for x^2: 17^2 - 8^2 = 289 - 64 = 225, and so x = 15.

n = 15

Irrational numbers are numbers that can not be written as a simple fraction. An example of one would be $\pi$ . Pi is about 3.14, but it goes on forever. You can not write pi as a simple fraction.
