Mathematics

The length of the park is 3.36km and the width is 2.68km

<u>Explanation:</u>

The park is rectangular.

Let L be the length of the park.

Let w be the width of the park.

According to the question:

L = 2w - 2

Area of the park = 9km²

We know:

Area of rectangle = length X width

9 = (2w - 2) X (w)

9 = 2w² - 2w

2w² - 2w - 9 = 0

On solving the quadratic equation we get:

w = 2.68 km

we know:

L = 2w - 2

So,

L = 2 (2.68) - 2

L = 3.36 km

Therefore, the length of the park is 3.36km and the width is 2.68km

Gechina Galvez shopped at a department store during the end-of-summer sale All luggage was marked down 35 percent. She purchased
Nikitich [7]

Answer:

The total sale price that Gechina paid was $5,274.71.

Step-by-step explanation:

Given that Gechina Galvez shopped at a department store during the end-of-summer sale in which all luggage was marked down 35 percent, and she purchased a suitcase that regularly sells for $74.95, a garment bag that regularly sells for $8,000, and a tote bag that regularly sells for $39.99, in order to know the total sale price, the following calculation has to be made:

100 - 35 = 65

(8,000 + 74.95 + 39.99) x 0.65 = X

8,114.94 x 0.65 = X

5,274.71 = X

Therefore, the total sale price that Gechina paid was $5,274.71.
