THE X-MEN’S LAST STAND: Will Heroes Reign or Collapse in This Epic Climax?!


\[ x^2 - 9 = (x - 3)(x + 3) \]
\[ rac{(x - 3)(x + 3)}{x + 3} = x - 3 \]
#### \( x - 3 \), \( x
\[ (2x + y) + (x - y) = 10 + 2 \]
\[ 3x = 12 \Rightarrow x = 4 \]
\[ 4 - y = 2 \Rightarrow y = 2 \]
#### \( x = 4, y = 2 \)
\[ f'(1) = 9(1)^2 - 10(1) + 2 = 9 - 10 + 2 = 1 \]
\[ V = rac{1}{3} \pi (3)^2 (7) = rac{1}{3} \pi \cdot 9 \cdot 7 = 21\pi \]
#### \( 21\pi \) cm³1. A cylindrical tank with a radius of 5 meters and a height of 10 meters is filled with water. If 1 cubic meter of water weighs 100
