Step by step:
2|x+6|+9=19
Subtract 9 from both sides.
2|x+6|=10
Divide both sides by 2
|x+6|=5
Use the definition of absolute value.
x+6=5
Subtract 6 on both sides
x=-1

Answer:
y = 39
Step-by-step explanation:
550 x 
= 
x 11 + y
550 x 
= x 11 x 11 + y
550 x x 
= 11 x 11 + y
550 = 11 x 11 + y
= 
x 11 + y
50 = 11 + y
50 - 11 = y
39 = y

Answer: 3 units
Step-by-step explanation:
the volume of a cone C = πr²h/3
C = 18π, h =2x, r = diameter/2 = 2x/2 =x
18π = π* x²* 2x/3
divide through by π
18 = x² * 2x/3
multiply through by 3
54 = 2x³
divide through by 2
27 = x³
x =∛27 = 3
x = 3 units = radius
