Answer: x - 12 is not a factor.
Step-by-step explanation:
The equation
x³ - 4x² - 4x + 16
To know which of the following is a factor , we continue to find the value of x and substitute into the equation and see the one that gives zero. The one that gives zero is the factor.
(a) x + 2
If x + 2 = 0
x = -2, now substitute for x in the equation and find out if it will be zero.
x³ - 4x² - 4x + 16 = (-2)³ - 4(-2)² - 4(-2) + 16.
= -8 - 16 + 8 + 16
= 0.
Therefore, x + 2 is a factor.
(b) x - 12
If x - 12 = 0, then x = 12
x³ - 4x² - 4x + 16
(12)³ - 4(12)² - 4(12) + 16
1728 - 576 - 48 + 16
= 1,120 , not a factor.
(c) x - 2
If x - 2 = 0, then x = 2
x³ - 4x² - 4x + 16
(2)³ - 4(2)² - 4(2) + 16
8 - 16 - 8 + 16
= 0, Therefore, x - 2 is a factor.
(d) x - 4
If x - 4 = 0, x = 4
x³ - 4x² - 4x + 16
(4)³ - 4(4)² - 4(4) + 16
48 - 48 - 16 + 16
= 0,therefore, x - 4 is also a factor.
Answer:
2 months
Step-by-step explanation:
$80 x 0.5 = $40
$80 + $40 = $120
$120 * 0.25 = $30
1st month - $120-$30 = $90
2nd month - $90-$22.5 = $67.5
I don't see how this is math related but let me ask why do you want to? Best friends don't normally leave when things get tough. I mean I do understand. And I will tell you my opinion if you truly want it as well. Jw.
Is this for money? Do you want an equivalent fraction? Please be more specific, but I'll imply a couple of options.
FOR MONEY:
50,000 euros is 55142.50 dollars
50,000 dollars is 45337.08 euros
Is 50,000 US dollars a good salary? In my opinion, yes. If you are a single person, and you work an office job from 9 to 5, then yes, that is a good salary.
MATH/NUMBERS:
50,000 = 100,000 ÷ 2
50,000 = 200,000 ÷ 4
50,000 = 25,000 × 2
50,000 = 12,500 × 4
There are other examples that could be used for both money and math, but I would not be able/do not have the time to list them all.

I hope this helps!
