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

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

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