Por favor, URGENTE!
$\sqrt{x - 14 } = 9$
$\sqrt{x} - 25 = - 7$
$7x { }^{2} = 112$

$x {}^{2} \div 27 = 3$

​

Answer 1

Explicación paso a paso:

$\sqrt{x - 14} = 9 \\ x - 14 = 9 {}^{2} \\ x = 81 + 14 \\ x = 95$

$\sqrt{x} - 25 = - 7 \\ \sqrt{x} = 25 - 7 \\ x = 18 {}^{2} \\ x = 324$

$7x {}^{2} = 112 \\ x {}^{2} = \frac{112}{7} \\ x {}^{2} = 16 \\ x = \sqrt{16} \\ x = 4$

$x {}^{2} \div 27 = 3 \\ x {}^{2} = 3 \times 27 \\ x {}^{2} = 81 \\ x = \sqrt{81} \\ x = 9$
