Porfa! es para mañana,gracias​

Answer 1

Respuesta:

A)

${x}^{2} + (4 \times - 17) = 32 \\ {x}^{2} - 68 = 32 \\ {x}^{2} = 32 + 68 \\ {x}^{2} = 100 \\ x = \sqrt{100} \\ x = 10$

B)

$\frac{ - 154}{ - 2} + \sqrt{m} = 79 \\ 77 + \sqrt{m} = 79 \\ \sqrt{m} = 79 - 77 \\ \sqrt{m} = 2 \\ m = {2}^{2} \\ m = 4$

C)

n+(-35/-7)-3^3+9n=-12

10n+5-3^3=-12

10n+5-27=-12

10n=-12-5+27

10n=10

n=1
