Best ResponseYou've already chosen the best response.5\[3=74=72^2=7z^2=7z^2=7z^2 \le 7z^2=z^27 \\ \le z^2+7=z^2+7=2^2+7=4+7=11\] this is both left and right hand sides

Best ResponseYou've already chosen the best response.1\[z^2=z^2 7 +7\leq z^2 7+7\] Hence \(z^2 7\geqz^27 \) Therefore \(z^2 7\geqz^27=47=3\)

Best ResponseYou've already chosen the best response.5\[7z^2 \le 7z^2 \le 7+z^2 \\ 7z^2 \le 7z^2 \le 7+z^2 \\ 72^2 \le 7z^2 \le 7+2^2 \\ 3 \le 7z^2 \le 11 \\ 3 \le z^27 \le 11 \] just in case that one thing was hard to read
