Answer:
Step-by-step explanation:
two step equation
n - 5/2 = 5
n = 5 + 5/2
n = 5 + 2.5
n = 7.5
-----------
check
7.5 - 5/2 = 5
7.5 - 2.5 = 5
5 = 5
the answer is good
Answer:
The answer is "1"
Step-by-step explanation:
Let 5 roman numbers are:
![\to I=1\\\\\to II=2\\\\\to III=3\\\\\to IV= 4\\\\\to V=5](https://tex.z-dn.net/?f=%5Cto%20I%3D1%5C%5C%5C%5C%5Cto%20II%3D2%5C%5C%5C%5C%5Cto%20III%3D3%5C%5C%5C%5C%5Cto%20IV%3D%204%5C%5C%5C%5C%5Cto%20V%3D5)
There square values are as follows:
![\to 1^2=1\\\\\to 2^2=4\\\\\to 3^2=6\\\\\to 4^2=16\\\\\to 5^2=25](https://tex.z-dn.net/?f=%5Cto%201%5E2%3D1%5C%5C%5C%5C%5Cto%202%5E2%3D4%5C%5C%5C%5C%5Cto%203%5E2%3D6%5C%5C%5C%5C%5Cto%204%5E2%3D16%5C%5C%5C%5C%5Cto%205%5E2%3D25)
The smallest square number is= 1.
Answer:
x = 22.5
Step-by-step explanation:
![\frac{BH}{DH} = \frac{HM}{HT} \\ \frac{6}{15 + 6} = \frac{9}{9 + x} \\ \frac{6}{21} = \frac{9}{9 + x} \\ 6(9 + x) = 9 \times 21 \\ 54 + 6x = 189 \\ 6x = 189 - 54 \\ 6x = 135 \\ x = \frac{135}{6} \\ x = 22.5](https://tex.z-dn.net/?f=%20%5Cfrac%7BBH%7D%7BDH%7D%20%20%3D%20%20%5Cfrac%7BHM%7D%7BHT%7D%20%20%5C%5C%20%20%5Cfrac%7B6%7D%7B15%20%2B%206%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B9%20%2B%20x%7D%20%20%5C%5C%20%20%5Cfrac%7B6%7D%7B21%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B9%20%2B%20x%7D%20%20%5C%5C%206%289%20%2B%20x%29%20%3D%209%20%5Ctimes%2021%20%5C%5C%2054%20%2B%206x%20%3D%20189%20%5C%5C%206x%20%3D%20189%20-%2054%20%5C%5C%20%206x%20%3D%20135%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B135%7D%7B6%7D%20%20%5C%5C%20x%20%3D%2022.5)
Subtract the 12x^2 first.
5x - 4 = 6
Add the four
5x = 10
Then divide the 5 from both sides
X = 2
A polynomial that has a degree of 2 is quadratic.
