Answer:
14
Step-by-step explanation:
-2x^3 - 2x^2 - 4x-2
Let x = -2
-2 (-2)^3 - 2 (-2)^2 -4(-2) -2
Exponents first
-2 (-8) -2 (4) -4(-2) -2
Then multiply
16 -8 +8 -2
Then add and subtract

Answer:

Step-by-step explanation:
x² + 6x + 9 = 12 → x² + 6x - 3
Since this Quadratic Expression is unfactorable, apply the <em>Quadratic</em><em> </em><em>Formula</em>:


√48 = √[3 × 16] = 4√3
½[4√3] = 2√3
Then attach half of -6 to it as well [-3]:
-3 ± 2√3

 <span>100 is not divisible by 3 when u divide 100 by 3 u get 33.333333...... not 3.33333..... 
the good explanation of your answer is that 0.999999....is equal to 1 
we can prove it by the following way: 
let x=0.9999.... 
then 10x = 9.999999..... 
subtract we will get 10x - x = 9.9999....- 0.99999...... 
which gives us 9x = 9 and therefore x =1 
i hope this will help u with your confusion.......  :)</span><span>
