The diagonals are perpendicular bisectors of each other. That is just the property of a Rhombus which can be proven.

Answer:

$\frac{2x}{x+7}$

Step-by-step explanation:

we have

$(\frac{x-3}{x+7})(\frac{2x}{x-3})$

When multiply two fractions:

Multiply the numerators of the fractions to get the new numerator.

Multiply the denominators of the fractions to get the new denominator

$(\frac{x-3}{x+7})(\frac{2x}{x-3})=\frac{(x-3)(2x)}{(x+7)(x-3)}$

(x-3) cancels out

KATRIN_1 [288]

Answer:

Step-by-step explanation:

Given

Jar contains 4 white and 4 black marbles

We randomly select 4 marbles out of which 2 are white and 2 are black

Probability that 2 white and 2 black marbles are selected is

$P=\frac{^4C_2\times ^4C_2}{^8C_4}$

$P=\frac{18}{35}$

The process is continue for n trails until we choose the correct order

i.e. we have to fail in n-1 trails

For exact n selection Probability is given by

$Req.\ Probability=Probability\ of\ failure\ in\ (n-1)\ trials\times Probability\ of\ getting\ exact\ order$

$=\left ( 1-\frac{18}{35}\right )^{n-1}\times \frac{18}{35}$
