Answer 1

Respuesta:

$x { }^{2} + 9 = 90 \\ x {}^{2} = 90 - 9 \\ x {}^{2} = 81 \\ x = \sqrt{81} \\ x = 9$

$w {}^{2} - 14 = 35 \\ w {}^{2} = 35 + 14 \\ w {}^{2} = 49 \\ w = \sqrt{49} \\ w = 7$

$4a {}^{2} = 16 \\ a {}^{2} = 16 \div 4 \\ a {}^{2} = 4 \\a = \sqrt{4} \\ a = 2$

$\frac{y {}^{2} }{3} = 12 \\ y {}^{2} = 12 \times 3 \\ y {}^{2} = 36 \\ y = 36 \div 2 \\ y = 18$

${x}^{2} - 18 = 126 \\ x {}^{2} = 126 + 18 \\ x { }^{2} = 144 \\ x = 144 \div 2 \\ x = 72$

$k \: {}^{2} + 104 = 120 \\ k {}^{2} = 120 - 104 \\ k {}^{2} = 16 \\ k = \sqrt{16} \\ k = 4$

$7t {}^{2} = 175 \\ t {}^{2} = 175 \div 7 \\ t {}^{2} = 25 \\ t = \sqrt{25} \\ t = 5$

$\frac{y {}^{2} }{4} = 25 \\ y {}^{2} = 25 \times 4 \\ y {}^{2} = 100 \\ y = \sqrt{100} \\ y = 10$
