X=27
81 = 3x= 27
So x means 27
It has 3 zeros, because its a polynomial of degree 3.
The value of s = 227 degrees. You can determine this because the area of a triangle is always 180 degrees. Since it is s-47, you add 47 to 180. This equals 227. Plug the number in and you get correct answer. 227-47=180
Hope this helps!
I believe the answer should be -4+x= -4x.
I hope this helps :)
