Answer:
9c+2
Step-by-step explanation:
Answer:
x^3+6x^2-17x+2
Step-by-step explanation:
(x-2)*(x^2+8x-1)
=x(x^2+8x-1)-2(x^2+8x-1)
=x^3+8x^2-x-2x^2-16x+2
collect like terms
= x^3+6x^2-17x+2
Eeeeeeeeeeeeeeeeeeeeeeeee
The number of sides is the same as the number of lines of symmetry and the order of rotational symmetry.
So, a regular decagon would have 10 lines of symmetry.
