31/84

Step-by-step explanation:

3/4 − 1/2 ( 1/3 + 3/7 )

1/3 + 3/7

Lcm: 21

(7 + 3(3))/21 = 16/21

1/2(16/21) = 8/21

3/4 - 8/21

Lcm: 84

(3(21) - 8(4))/84

(63 - 32)/84

31/84

Mathematics

x = - 12, 3

Step-by-step explanation:

By tangent secant theorem:

$x(x + 9) = {6}^{2} \\ \\ {x}^{2} + 9x = 36 \\ \\ {x}^{2} + 9x - 36 = 0 \\ \\ {x}^{2} + 12x - 3x - 36 = 0 \\ \\ x(x + 12) - 3(x + 12) = 0 \\ \\ (x + 12)(x - 3) = 0 \\ \\ x + 12 = 0, \: \: x - 3 = 0 \\ \\ x = - 12, \: \: x = 3 \\ \\$
