Step-by-step explanation:

-10 or -20 satisfies the equation.

But when you substitute 10 in:

30-40<-50+8

The magnitude of a ra representation of a number as the product of a number that is greater than or equal to 1 but less than
kirill [66]

Answer:

<h3>C. Scientific Notation</h3>

Step-by-step explanation:

Since the number in question is greater than or equal to 1 but less than

10, we can choose any number between 1 and 10, lets take 3 for example.

If we take the product of 3 and an integer power of 10 number without regard to its sign, this can be expressed mathematically as shown;

3 * 10^{-5} where the power of 10 is -5. Note that any  real number can be used as the power since we are not regarding the sign (Here we used -5). The expression formed according to the expression in question is a SCIENTIFIC NOTATION i.e 3 * 10^{-5} gives us a scientific notation.

<em>Scientific notation is a means by which we represent very large or small numbers that are difficult to represent using a decimal notation</em>

Solve with Quadratics
leonid [27]

Answer:

x = 1 ± \sqrt{6}

Step-by-step explanation:

Given

2x² - 4x = 10 ( divide through by 2 )

x² - 2x = 5

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 1)x + 1 = 5 + 1

(x - 1)² = 6 ( take the square root of both sides )

x - 1 = ± \sqrt{6} ( add 1 to both sides )

x = 1 ± \sqrt{6} ← exact solutions
