Answer 1

Explicação passo-a-passo:

$3 {}^{2} = ( 2 + x) \times 2 \\ 9 = 2x + 4 \\ 2x = - 4 + 9 \\ 2x = 5 \\ x = \frac{5}{2}$

${y}^{2} =( 2 + x) \times x \\ {y}^{2} = (2 + \frac{5}{2} ) \times \frac{5}{2} \\ {y}^{2} = \frac{9}{2} \times \frac{5}{2} \\ {y}^{2} = \frac{45}{4} \\ y = \sqrt{ \frac{45}{4} } \\ y = \frac{ \sqrt{45} }{2}$
