Ответ:
x² - 4x - 5
Step-by-step explanation:
Recall:
Area of a square = s² ; where s = side length
Side length of gold square = (x - 2)
Width = Side length of red = 3 inches
Area of the red part :
Area of gold part - Area of red part
(x - 2)² - 3²
(x - 2)(x - 2)
x² - 2x - 2x + 4 - 9
x² - 4x + 4 -9
x² - 4x - 5
Hence, area of red part is : x² - 4x - 5
