donโ€™t worry youโ€™ll get the hang of it eventually! there are 3 key elements of a circle you have to remember: circumference=the perimeter diameter= the length across the middle radius= the length from the middle to the edge when working with circles, there is a special number called pi (ฯ€). If youโ€™re using a calculator there is a button that represents pi (shift + x10). if youโ€™re not using a calculator then you can represent pi as 3.14 now to find the circumference, thereโ€™s a formula you need to use. you can use: pi x diameter or 2 x pi x radius hope this helps!

Let f(x) = 3x^3 + (b+3)x^2 - (4b^2+b-7)x-4 Then (x-b) is a factor of f(x) if and only if f(b)=0, because if (x-b) is a factor of f(x) then we can wr...
