... Note: we assume here that x itself must be greater than 1; hence 1 is not considered square-free. However, one must be alert to the particular context in which “square-free” is used as to whether this is considered the case. The name derives from the fact that if any ai were to be greater than or eq ...

Graph Colouring
... Every planar graph G has χ(G) ≤ 4. That is, a planar graph can always be coloured with four or fewer colours. The Four Colour Theorem engaged the interest of such famous mathematicians as Hamilton, De Morgan, Cayley and Birkhoff. It also prompted a famous incorrect proof that survived from 1879 to 1 ...

... Part C, sample response 1: "A complete solution needs two inequalities, one for when x < 20 and one for when x > 20. When x ≤ 20: 200 < 80 + 8x → 120 < 8x → 15 < x. When x > 20: 200 + 10(x – 20) < 80 + 8x → 200 + 10x – 200 < 80 + 8x → 10x < 80 + 8x → 2x < 80 → x < 40. Gutter Guys is less expensive f ...
