I hope it will be useful.
Hint:
Since its an isosceles right angled triangle! (Apply the properties)
Or, you can use Pythagoras theorem.
(2x^2=9 v.i.z., on rationalizing 1.5*√2)
Two multiplied by x plus three plus six is equal to three multiplied by x subtracted by nine
2,3,4
1st way: 6*2oz=12oz
2nd way: 3*2oz+2*3oz=12oz
3rd way: 4*2oz+4oz=12oz
4th way: 2*2oz+2*4oz=12oz
5th way: 4*3oz=12oz
6th way: 2*3oz+2oz+4oz=12oz
7th way: 3*4oz=12oz
Stuart can combine 2oz, 3oz and 4oz weigths 7 different ways to get 12oz.
