Answer:

166.27 m2

Step-by-step explanation:

area of hexagon = \frac{3*\sqrt{3} }{2}*a^{2} where a = length of 1 side

this hexagon is made of 6 equivalent triangle

consider ABC triangle

let AC length be x

<em>AB = 2 * AC = 2x = a</em>

bc^{2} = ab^{2} - ac^{2} \\(4\sqrt{3})^{2} =(2x)^{2}  - x^{2} \\48=3*x^{2}\\ 16=x^{2} \\x=4

Hence a = 8

<u>hence area of hexagon = </u>\frac{3*\sqrt{3} }{2}<u>*</u>a^{2}<u> =  </u>\frac{3*\sqrt{3} }{2}<u> * </u>8^{2}<u> = 166.27 m2</u>

Answer:

6 of x and 5 of y

Step-by-step explanation:

x = number of closets of the first type

y = number of closets of the second type

1200 = 100x + 120y

100 = 10x + 8y

10x = 100 - 8y

10x(100 - 8y) + 120y = 1200

1000 - 80y + 120y = 1200

40y = 200

y = 5

100 = 10x + 8×5 = 10x + 40

60 = 10x

x = 6

20x + 24y = max

20×6 + 24×5 = 120 + 120 = 240

Points A, B, and C are collinear. Point B is between A and C. BC=8x+709. AB=487+5x. AC=91. Find BC.
Zolol [24]

Answer:

<h3>            BC = 29</h3>

Step-by-step explanation:

Point B is between A and C and the points A, B, and C are collinear so:

AB + BC = AC

487 + 5x + 8x + 709 = 91

  13x + 1196 = 91

       - 1196      - 1196

   13x  =  - 1105

     ÷13     ÷13

    x = - 85

BC =  8x + 709 = 8(-85) + 709 = - 680 + 709 = 29
