The area of the Rhombus is 162√3 sq.unit , Option A is the correct answer.

<h3>What is a Rhombus ?</h3>

A rhombus is a polygon , which has four equal sides , its diagonal bisect each other at 90 degree.

Let x be the half of the other diagonal.

tan 60 = x / 9

x = 9 tan 60

x = 9√3

Area of the Rhombus = (d1 * d2 /2 )

d1 and d2 are the length of the diagonal.

Area of the Rhombus = (9*2)(2 *9√3)/2

Area of the Rhombus =162√3 sq.unit

(X-3) (2x-3)= (x-3) (x+1) solve for x

yanalaym [24]

$(x - 3)(2x - 3) = (x - 3)(x + 1)$

Do the multiplication both sides,

$2 {x}^{2} - 9x + 9 = {x}^{2} - 2x - 3$

Arrange the terms to LHS according to their variables,

$2 {x}^{2} - {x}^{2} - 9x + 2x + 9 - 3 = 0 \\ {x}^{2} - 7x + 6 = 0$

Factorise this polynomial

${x}^{2} - 6x - 6x + 6 = 0 \\ x(x - 6) - (x - 6) = 0 \\ (x - 1)(x - 6) = 0$

So what we notice here is when you're multiplying two numbers you're getting 0 as answer.

So one of them must be 0.

If (x-1) is 0
then x = 1

similarly,

x-6=0

then, x= 6.

So the possible values of x are 1 and 6.

Natsumi went on a business lunch. The pretax bill was $55.60. She decided

igomit [66]

8.25% of 55.60 = 4.58700

We round that number to 4.59

(I am assuming the tip is based on the amount of the pretax bill.)

15% of 55.60 = 8.34

So $55.60 + $4.59 + 8.34 = $68.53

The bill would be $68.53.
