Answer:

  D)  54

Step-by-step explanation:

Put the numbers where the variables are and do the arithmetic.

  2[(x -1) +2xy]

  = 2[(4 -1) +2(4)(3)]

  = 2[3 +24]

  = 2(27) = 54 . . . . matches choice D

Answer:

  • 54

Step-by-step explanation:

We know that:

  • Given expression: 2[(x - 1) + 2xy]
  • x = 4
  • y = 3

Solution:

  • 2[(x - 1) + 2xy]
  • => 2[(4 - 1) + 2(4)(3)]
  • => 2[3 + 2(4)(3)]
  • => 2[3 + 24]
  • => 2[27]
  • => 54

Hence, Option D is correct.
