A rectangular window is 4x inches wide and 8x inches long. What is an expression for the distance from one corner of the window to the opposite corner? Give your answer as a simplified radical.

Step-by-step explanation:

Pythagorean theorem

a² + b² = c²          a = 4x     b=8x

c = √(a² + b²)

c =√((4x)² + (8x)²)

  = √(16x² + 64x²)

  = √80x²

  = √(16×5)x²

  = 4x√5

hi, i am not sure about this one but i think its d,
