Answer 1

Respuesta:

$\frac{a}{b} = \frac{c}{d} = 7 \\ e = ( {a}^{2} + {c}^{2} ) \div ( {b}^{2} + {d}^{2} ) \\ e = ((7b) {}^{2} + (7d) {}^{2} ) \div ( {b}^{2} + {d}^{2} ) \\ e = \frac{49 {b}^{2} + 49 {d}^{2} }{ {b}^{2} + {d}^{2} } \\ e = \frac{49( {b}^{2} + {d}^{2} )}{( {b}^{2} + {d}^{2}) } \\ e = 49$
