Answer:

f(1) =  {(1)}^{3}  + 3 {(1)}^{2}  - 9(1) + 5 \\ (x - 1) = 0 \rightarrow \: x = 1 \\\frac{{x}^{3 } + {3x}^{2} - 9x + 5}{x - 1}  =  {x}^{2}  + 4x - 5 \\ (x + 5)(x - 1) = 0 \\ x =  - 5 \: or \: x = 1 \\   \color{red}\boxed{x_{1} = 1} \\\color{yellow} \boxed {x_{2} = 1} \\    \color{green}\boxed{x_{3} =  - 5}

The answer would be C and F

The diagram shows a regular polygon. What is the value of x?
IrinaVladis [17]

Answer:

sum of the measure of the angles in a polygon with n sides is (n - 2)*180°. If the angles of a given polygon are given in terms of x, it is possible to find the value of x by using this formula. The number of sides that the polygon has is given, so first plug that value into the formula (n - 2)*180°.
