Because I could not find it reiny!!!!
To find the expression that represents the area of the window, we can use the formula given: area = base * height.
In this case, the base of the window is the width (x+7) inches, and the height is the length (x+9) inches.
So the expression representing the area of the window would be:
Area = (x+7) * (x+9)
Now, let's substitute x with 8 inches, as given in the question:
Area = (8+7) * (8+9)
Area = 15 * 17
Area = 255 square inches
Therefore, the area of the window using the expression (x+7) * (x+9) when x = 8 inches is 255 square inches.
