Step-by-step explanation:

<h2>A^2 + B^2 = C^2 </h2>

A and B are the legs of the triangles.

C is the hypotenuse.

12^2 + x^2 = 20^2

144 + x^2 = 400

-144            -144

x^2 = 256

x = 16

Is x^(-2)+5 a polynomial expression? Why or why not?
SIZIF [17.4K]
Thanks for the correction. Answer: No, x^(^-^2^)+5 is a polynomial expression because it has a break between numerical exponents. It goes from 0x^1 to x^2, which makes it in the form of x^{2} to x^0 which means that it is NOT a polynomial.
