Factorise $h^2-12h+32$ . 

Consider the simultaneous equations.
 $2x+3y=9$  

 $5x-3y=12$  

Write down the value of x.

 $x=.\ .\ .\ .\ .\ .$  

Convert 12500 cm² to m².

. . . . . . m²

Using the graphs, solve these simultaneous equations.

 $y+2x=6$ 
 $4y+3x=4$  

Solve   $\frac{1+5x}{2}=\frac{11x}{4}$ 

 $x\ =\ .\ .\ .\ .\ .\ .\$
