Re-write this calculation using brackets to make it true (3 multiple2multiple6+2-48 6multiple6 80  Simplify the following expressions using the correct order fo operations.  Write an expressions for the area of a rectangle 9 units long a (2x-7)units wide. 
  
  Solution
Length of the rectangle = a
width of the rectangle = a (2x-7)
Area of the rectangle = length*width
=> A = a* a(2x-7)
=> A = a^2 (2x-7)
=> A= 2x a^2 - 7a^2
