Answer:
10.99
Step-by-step explanation:
![tan20 = \frac{ac}{bc} \\ bc = \frac{ac}{tan20} \\ = \frac{4}{tan20} \\ = 10.99](https://tex.z-dn.net/?f=tan20%20%3D%20%20%5Cfrac%7Bac%7D%7Bbc%7D%20%20%5C%5C%20bc%20%3D%20%20%5Cfrac%7Bac%7D%7Btan20%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B4%7D%7Btan20%7D%20%20%5C%5C%20%20%3D%2010.99)

Answer: g(-x) = 2x^2 +5x + 5
Step-by-step explanation:
This Is a topic under functions in mathematics, it deals with substituting "x" for the new entity that has been placed in the new function you're asked to look for.
Hence, to solve this, we simply substitute "-x" for "x" wherever "x" appears in the equation.
By doing so, we go straight to the given function.
2x^2 -5x + 5
And we go ahead with our substitution which goes thus:
2(-x^2) -5(-x) + 5
On simplifying, we then finally have have:
2x^2 +5x + 5.
This means:
g(-x) = 2x^2 +5x + 5
6,440 divided by 28 is 230.....
