Let y= x 2 x+ 3 x 6 x+ 4 x 13 x x 2 x+ 3 x 6 x+ 4 x 13 x , then:

Options

  1. Aif x= 72 , then y= 2 -1
  2. Bif x= 24 , then y= 2 +1
  3. Cif x= 108 , then y=2+ 3
  4. Dif x= 5 108 , then y=2- 3

Correct answer

B. if x= 24 , then y= 2 +1

Step-by-step solution

y= x- 3 x+ 3 x- 9 x+ 9 x- 17 x 3 x- x+ 9 x- 3 x+ 17 x- 9 x y= x- 17 x 17 x- x = 2 9 x 8 x 2 8 x 9 x = 9 x (a) and (b) are correct.
