The number of ways to select 3 dishes from 6 :

Total outcomes :                    

If applesauce and broccoli is already selected , then we need to select only one dish out of remaining 4 dishes.

Number of ways to select 1 dish from 4 :

Favorable outcomes:  

Now, the theoretical probability that applesauce and broccoli will both be offered on Monday :-

Solve for x. use the completing the square method.<br><br>x^2+8x=5
jok3333 [9.3K]
x^2+8x=5

x^2+8x + ( \frac{8}{2} )^2 =5 +  (\frac{8}{2} )^2

x^2+8x + (4)^2 =5 +  (4)^2

(x+ 4)^2 =21

x+ 4 = \pm \sqrt{21}

x = \sqrt{21} - 4 \ or \ x=  -\sqrt{21} - 4

x = 0.58 \ or \ x= -8.58

Struggling lol. Any help would be appreciated!
Alekssandra [29.7K]

Answer:

Heptagon = 84 ft²

Octagon  = 186 yd²

Triangle = 48√3 m²

Step-by-step explanation:

\textsf{area of a regular polygon}=\dfrac12ap

where:

  • a = length of apothem
  • p = perimeter

<u>Heptagon</u>

a = 5.0 ft

p = 33.6 ft

⇒ area = 1/2 x 5.0 x 33.6 = 84 ft²

<u>Octagon</u>

a = 7.5 yd

p = 8 x 6.2 = 49.6 yd

⇒ area = 1/2 x 7.5 x 49.6 = 186 yd²

<u>Triangle</u>

Formula for the apothem of an equilateral triangle :

a=\dfrac{s}{2\sqrt{3}}  where s = side length

a = 4, so:

4=\dfrac{s}{2\sqrt{3}}

\implies 8\sqrt{3}=s

Now we know the side length, we can calculate the perimeter (p):

p = 3 x 8√3 = 24√3

⇒ area = 1/2 x 4 x 24√3 = 48√3 m²
