Answer:
21.9
Step-by-step explanation:
The altitude of an isosceles triangle bisects the base. So, x represents the hypotenuse of a right triangle with legs of 9 and 20. It can be found using the Pythagorean theorem:
x^2 = 9^2 +20^2 = 81 +400
x = √481 ≈ 21.932
The length x is about 21.9 units.

Given:
Ratio of tulips to roses = 2:1
Total number of flowers = 18
To find:
The number of tulips.
Solution:
Let the number of tulips and roses are 2x and x respectively.
According to the question,
![2x+x=18](https://tex.z-dn.net/?f=2x%2Bx%3D18)
![3x=18](https://tex.z-dn.net/?f=3x%3D18)
Divide both sides by 3.
![x=\dfrac{18}{3}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B18%7D%7B3%7D)
![x=6](https://tex.z-dn.net/?f=x%3D6)
Now,
Number of tulips ![=2(6)](https://tex.z-dn.net/?f=%3D2%286%29)
![=12](https://tex.z-dn.net/?f=%3D12)
Therefore, the number of tulips is 12.
Answer:
Step-by-step explanation:
Alright, lets get started.
The given equation is :
![e^{3x+6} =8](https://tex.z-dn.net/?f=e%5E%7B3x%2B6%7D%20%3D8)
taking log on both side
![lne^{3x+6}=ln8](https://tex.z-dn.net/?f=lne%5E%7B3x%2B6%7D%3Dln8)
![(3x+6)lne=ln8](https://tex.z-dn.net/?f=%283x%2B6%29lne%3Dln8)
Plugging the value of ln e as 1
![3x+6=ln8](https://tex.z-dn.net/?f=3x%2B6%3Dln8)
Subtracting 6 in both sides
![3x+6-6=ln8-6](https://tex.z-dn.net/?f=3x%2B6-6%3Dln8-6)
![3x=ln8-6](https://tex.z-dn.net/?f=3x%3Dln8-6)
Dividing 3 in both sides
