Step-by-step explanation:
![x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{ - 5 + - \sqrt{ {5}^{2} - 4(5) } }{2} \\ x = \frac{ - 5 + - \sqrt{25 - 20} }{2} \\ x = \frac{ - 5 + - \sqrt{5} }{2}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B%20-%20b%20%2B%20%20-%20%20%5Csqrt%7B%20%7Bb%7D%5E%7B2%7D%20-%204ac%20%7D%20%7D%7B2a%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B%20-%205%20%2B%20%20-%20%20%20%5Csqrt%7B%20%7B5%7D%5E%7B2%7D%20-%204%285%29%20%7D%20%7D%7B2%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B%20-%205%20%2B%20%20-%20%20%5Csqrt%7B25%20-%2020%7D%20%7D%7B2%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B%20-%205%20%2B%20%20-%20%20%5Csqrt%7B5%7D%20%7D%7B2%7D%20)
Therefore, the zeroes would be:
![x1 = \frac{ - 5 + \sqrt{5} }{2} \\ x2 = \frac{ - 5 - \sqrt{5} }{2}](https://tex.z-dn.net/?f=x1%20%3D%20%20%5Cfrac%7B%20-%205%20%2B%20%20%5Csqrt%7B5%7D%20%7D%7B2%7D%20%20%5C%5C%20x2%20%3D%20%20%5Cfrac%7B%20-%205%20-%20%20%5Csqrt%7B5%7D%20%7D%7B2%7D%20)

Answer:
( 10 x + 10 ) = 110
Step-by-step explanation:
As you can see this following diagram shown a vertical angles which are angles that are opposite of each other when two lines cross. You can also see it kind of look like a "x". Vertical angles also means that they have the same angle measure. A example is if this angle is "110" then the other sides equal to "110''.
Hence, the equation we can be used to solve for x in the following diagram is:
( 10 x + 10 ) = 110

Answer:
15.13
Step-by-step explanation:
To find diameter, divide circumference by pi or 3.14
I'm going to change the fraction to a decimal, so 47.5
47.5/3.14 = 15.1273885
Round to nearest hundredth gives you 15.13
