The polynomial cannot be factored in because it exists prime. Since 112 exists not a perfect square number so we cannot estimate the factors of the given equation.
<h3>What is a quadratic equation?</h3>
In a quadratic equation ax² + bx + c = 0
when (b² - 4ac) exists a perfect square only then we can factorize the equation.
In the given equation x² - 8x - 12 we have to determine the value of
b² - 4ac
From the equation, we get b = -8 and c = -12
b²- 4ac = (-8)² - 4(1)(-12)
= 64 + 48 = 112
Since 112 exists not a perfect square number so we can not estimate the factors of the given equation.

Answer:
5 gigabyte
Step-by-step explanation:
Let the GB data at which the charge for both company is same be x
For Kodu
monthly fixed charge = $50
Per GB data charge over limit = $36
charge for X GB data = Per GB data charge over limit *x = $36*x = 36x
Total charge for Kodu for x gb data = monthly fixed charge +charge for X GB data = $50 +$36
For Fidu
monthly fixed charge = $35
Per GB data charge over limit = $39
charge for X GB data = Per GB data charge over limit *x = $39*x = 39x
Total charge for Fidu for x gb data = monthly fixed charge +charge for X GB data = $35 +$39
Given that at at X GB data charge for both the company is same then
50 +36x = 35 +39x
39x - 36x = 50-35
=> 3x = 15
=> x = 15/3 = 5
Thus, at 5 GB over the limit, charge for both the company will be same.

Answer:
$ 1,057.22
Step-by-step explanation:
A = $ 1,057.22
A = P + I where
P (principal) = $ 800.00
I (interest) = $ 257.22
Answer : Second Option is correct.
Explanation :
Since we have given in the figure ,
AE=12 units
AD=9 units
EB=4 units
DC=x units
By using the BPT theorem, which states that
"If a line is drawn parallel to one side of a triangle in distinct point , the other sides are divided in the same ratio."
So, here we have a ΔABC,
in which DE║BC as shown in the figure ,
so, by using the BPT we get,
Hence, length of DC = 3 units .
