Suppose that \( y \) varies directly with \( x \), and \( y=15 \) when \( x=6 \). (a) Write a direct variation equation that relates \( x \) and \( y \). Equation: \( \frac{5}{2} \) (b) Find \( y=\frac{40}{2} \)

Show A and Show B are two television shows. The number of eplsodes of each show are consecutive integers whose sum is 233 . If there are more episodes of Show B, how many episodes of each were there? Show A Show B episodes Submit Answer

1) \( y=6 x \)

Factorise coumpletely. \( 21 a^{2}+28 a^{b} \)

A. Déterminer la forme canonique de chacun des polynômes suivants : 1. \( P(x)=3 x^{2}-6 x+9 \) 2. \( P(x)=-5 x^{2}+3 x+12 \) 3. \( P(x)=9 x^{2}-7 x \)

(b) \( 27 x^{2}-3 y^{2} \)
