Step-by-step explanation:
(1)
x² - 6 = 2 - 18x ( add 18x to both sides )
x² + 18x - 6 = 2 ( add 6 to both sides )
x² + 18x = 8
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(9)x + 81 = 8 + 81
(x + 9)² = 89
(2)
(x + 9)² = 89 ( take square root of both sides )
x + 9 = ±
( subtract 9 from both sides )
x = - 9 ±

Answer:
-x^7
Step-by-step explanation:
.21 cents divide 1.68 by 8 and you will get .21 cents.
We know that
[volume of a sphere]=(4/3)*pi*r³
r=12 in
[volume of a sphere]=(4/3)*3.14*12³-----> 7234.56 in³------> 7235 in³
the answer is the option
<span>D) 7,235 in</span>³
