Question

Помогите пожалуйста СРОЧНО

Answer 1

$1) \frac{22.5 {}^{2} - {2.5}^{2} }{ {6}^{2} + {8}^{2} } = \frac{(22.5 - 2.5)(22.5 + 2.5)}{36 + 64} = \frac{20 \times 25}{100} = \frac{500}{100} = 5$
$2) \frac{ {32.5}^{2} - {2.5}^{2} }{ {3}^{2} + {4}^{2} } = \frac{(32.5 - 2.5)(32.5 + 2.5)}{9 + 16} = \frac{30 \times 35}{25} = \frac{1050}{25} = 42$

Answer 2

$\frac{22,5^2-2,5^2}{6^2+8^2}=\frac{(22,5-2,5)(22,5+2,5)}{36+64}=\frac{20\cdot 25}{100}=\frac{500}{100}=5$

$\frac{32,5^2-2,5^2}{3^2+4^2}\frac{(32,5-2,5)(32,5+2,5)}{9+16}=\frac{30\cdot 35}{25}=\frac{1050}{25}=42$
