Answer 1

Explaination:

The missing dimension is: The total height - 2 times (height of the frame)

6w² + 8 - 2(w² - 3w + 2)

6w² + 8 - 2w² + 6w - 4

Answer:

4w² + 6w + 4

Answer 2

• 4w² + 6w + 4

Explanation:

The missing dimension is:

• The total height - 2× (height of the frame)
• 6w² + 8 - 2(w² - 3w + 2) =
• 6w² + 8 - 2w² + 6w - 4 =
• 4w² + 6w + 4
