Although the statements are not given, allow me to provide supplements to your understanding of polynomial equations. Because the graphs of two polynomial equations (let's name then f(x) and g(x)), then they do not share coordinate planes or points. If they do not share any points by intersection, then the system of equations does not have a solution. Therefore, Kelly's statement is correct.
Using a^2+b^2=c^2we can substitute a and b in which is 34^2+8^2=c^21156+64=c^21220 = c^2Now we need to square both sides√1220 = √c^234.9284983931 ----> 34.9334.93 = cc = 34.93
