In the figure below, L N equals 4 x minus 7 and M O equals 2 x plus 13. For which value of x is the figure a rectangle?

Georgia [21]

For this case we have the following data:

$LN = 4x-7$

$MO = 2x + 13$

So that the figure can be a rectangle, its diagonals must be equal, that is, $LN = MO$

In this way we have:

$4x-7 = 2x + 13$

Clearing x we have:

$4x-2x = 13 + 7 \\2x = 20$

$x=\frac{20}{2} \\x = 10$

Thus, x must be equal to 10 so that the figure is a rectangle.

Answer:

$x = 10$

Answer:

Step-by-step explanation:

let a = 5

a² + 7 | Original equation

5² + 7 | Substitution of a as 5

25 + 7 | 5 to the power of 2 is 25, as 5*5 = 25.

32 | 25 + 7 = 32

Which of the following is the product of the rational expressions shown here? 1/x+2 * x/x-2 A.) x/x^2-4 B.) x+1/x^2-4 C.) x+1/2x

Inessa [10]

Answer:

Step-by-step explanation:

$\frac{1}{x+2}*\frac{x}{x-2}=\frac{1*x}{(x+2)(x-2)}\\\\\\=\frac{x}{x^{2}-2^{2}}\\\\\\=\frac{x}{x^{2}-4}$
