Which expression is not equivelent to 7

We just started the introduction into circles and i have no idea how to do this.

Which of these tools or constructions is used to inscribe a hexagon inside a circle?

Afunction g(x) has x-intercepts at (, 0) and (6, 0). which could be g(x)? g(x) = 2(x + 1)(x + 6) g(x) = (x – 6)(2x – 1) g(x) = 2(x – 2)(x – 6) g(x) = (x + 6)(x + 2)
