Answer:
3.272727
Step-by-step explanation:
6^2/(3+9)
= 6^2/(11)
= 36/(11)
= 3.272727
Answer:
I think
11cm²-5cm²=121+25
and the square root of that will give you 12.08
and that's the answer
Answer:
1.
![\frac{n^{2} - 1 }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bn%5E%7B2%7D%20-%201%20%7D%7B2%7D%20)
2.
![\sqrt{29}](https://tex.z-dn.net/?f=%20%5Csqrt%7B29%7D%20)
Step-by-step explanation:
Area of triangle=1/2×b×h
=
![\frac{1}{2} \times (n - 1)(n + 1)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20%28n%20-%201%29%28n%20%2B%201%29)
![\frac{( {n}^{2} + n - n - 1) }{2 }](https://tex.z-dn.net/?f=%20%5Cfrac%7B%28%20%7Bn%7D%5E%7B2%7D%20%2B%20n%20-%20n%20-%201%29%20%7D%7B2%20%7D%20)
![\frac{ {n}^{2} - 1 }{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7Bn%7D%5E%7B2%7D%20-%201%20%7D%7B2%7D%20)
2. Area of triangle=14
![\frac{ {n}^{2} - 1 }{2} = 14](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7Bn%7D%5E%7B2%7D%20-%201%20%7D%7B2%7D%20%20%3D%2014)
![{n}^{2} - 1 = 28](https://tex.z-dn.net/?f=%20%7Bn%7D%5E%7B2%7D%20%20-%201%20%3D%2028)
![{n}^{2} = 29](https://tex.z-dn.net/?f=%20%7Bn%7D%5E%7B2%7D%20%20%3D%2029)
![n = \sqrt{29}](https://tex.z-dn.net/?f=n%20%3D%20%20%5Csqrt%7B29%7D%20)
