Question 619070
The diagram shows a rectangle , (2x-1)cm (x+4)cm
One of the sides is 11cm.
work out the two possible values of x 
.
One possible solution is when
2x-1 = 11
2x = 12
x = 6 
dimensions are then 11cm by 10 cm
.
Second possible solution is when:
x+4 = 11
x = 7
dimensions are then 13cm by 11 cm
.
Answer: the two possible values of x are 6 and 7
