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
The length of the second leg is 16.
C. This is because you have equal odds, so you are not leaning heavily in one direction!
Standard form: 7z^4-6z^2-6z
This IS a polynomial, it's degree is 4 and has 3 terms
