Answer 1

Respuesta:

82

Explicación paso a paso:

$50 \times {6}^{2} = x. {5}^{2} \\ 50 \times 36 = x.25 \\ 1800 = 25x \\ x = 72$

$50 \times {6}^{2} = 18 \times {y}^{2} \\ 50 \times 36 = 18 {y}^{2} \\ 1800 = 18 {y}^{2} \\ \frac{1800}{18} = {y}^{2} \\ 100 = {y}^{2} \\ \sqrt{100} = y \\ 10 = y$

x+y=72+10=82
