This statement is true. For example:
is an example of a quadratic equation in standard form. a, b, and c are all real numbers,
while a ≠ 0.
is another example. a, b, and c are real numbers (b = 0), and a ≠ 0.
would not be an example of a quadratic equation in standard form. a is not a real number.
is not an example because a = 0.
In order to find what x equals, we need to make it so x is on one side and what it equals, on the other.
First of all, we subtract 10 from both sides. You will now have:
x^3 - 5x^2 + 2x - 10 = 0
You will now either factor it which is recommended or use the Cubic Formula which is pretty difficult to memorize and to solve. I will now factor it.
( x - 5) ( x^2 + 2 ) = 0
You can now take both of the expressions inside and make them equal to zero and solve them.
x - 5 = 0x = 5
x^2 + 2 = 0x^2 = -2

The second option is irrational and uses an imaginary number which you will start seeing in Alegbra II (or already have if you are taking it or have already passed it), so the first one which is 5, is the correct answer.
Answer: 5
Answer:
$14.11
Step-by-step explanation:
to get your answer you multiply
13.31 x 6% = 0.7986 round that off to .80
then you add 13.31 + .80 = 14.11
Answer:
Units of Length
10 millimeters (mm) = 1 centimeter (cm)
10 decimeters = 1 meter (m)
10 decimeters = 1000 millimeters
10 meters = 1 dekameter (dam)
