Answer:

  D.  2x² +74x +644

Step-by-step explanation:

The first number can be written as (x +23).

The second number can be written as 2(x+23)-18 = (2x +28).

The product of these numbers can be found using the distributive property:

  P(x) = (x +23)(2x +28) = x(2x +28) +23(2x +28)

  = 2x² +28x +46x +644 . . . . . . . already you know the correct answer choice

  P(x) = 2x² +74x +644
