4<|x+2|<6 jawabannya ​

Jawab:
Hp = {x | -8 < x < -6  ∪  2 < x < 4, x∈R}

Penjelasan:
4 < |x+2| < 6
|x+2| > 4                   |x+2| < 6
x+2 < -4, x+2 > 4     -6 < x+2 < 6
x < -4-2, x > 4 – 2     -6-2 < x < 6-2
x < -6     x > 2           -8 < x < 4
x < -6     x > 2           x > -8   x < 4

x < -6     x > -8          x > 2    x < 4
-8 < x < -6                2 < x < 4

Hp = {x | -8 < x < -6  ∪  2 < x < 4, x∈R}
