Factorise

 $18a+3$  

•  $3\left(6a+1\right)$  

•  $6\left(3a\right)+3$  

•  $3\left(6a\right)+3$  

•  $6\left(3a+1\right)$  

Express

 $\frac{5}{6y}-\frac{3x-5}{12y}$  as a single fraction in its lowest form.

•  $\frac{\left(15-3x\right)}{12y}$  

•  $\frac{\left(5-x\right)}{4y}$  

•  $\frac{\left(15+3x\right)}{12y}$  

•  $\frac{\left(5-x\right)}{4y}$  

Expand

 $-5\left(a-c\right)$  

Simplify  $\frac{3x+6}{x^2-4}\div\frac{x+2}{x-2}$  

•  $\frac{3}{x-2}$  

•  $\frac{x+2}{3}$  

•  $\frac{3}{x+2}$  

•  $\frac{x-2}{3}$  

Factorise completely  $4-100n^2$  

Simplify  $\left(m-4n\right)\left(m+4n\right)-m^2$  

•  $x+\frac{y}{2}$  

•  $x-\frac{y}{2}$  

•  $\frac{\left(x+y\right)}{2}$  

•  $\frac{\left(x-y\right)}{2}$  

Factorise

 $2ae+3af-6de-9df$  

It is given that   $\frac{2}{5}$  of Alex’s money is equal to   $\frac{1}{4}$  of Benny’s money. If Benny has RM100, calculate the total amount of money for both of them. No need to write the unit (do not write RM in your answer)

Puan Maria has a piece of carpet, (3r-2) metre in length and (r+1) metre in width. Calculate the area of her carpet.

• $3r^2+r-2$

• $3r^2+r+2$

• $3r^2-r-2$

• $3r^2-r+2$

Azimah bakes a square layered cake measuring (3x+2) cm long and (x+2) cm wide. She cuts the cake into 6 equal parts along the length and 3 equal parts along the width. Determine the area of of each piece of cake in algebraic form.
