It seems like you are trying to find the area of a rectangle with length (x + 7) and width (x + 3). In order to find the area, you need to multiply the length and width. So the area would be:
Area = (x + 7)(x + 3)
To simplify the expression, you can expand it using the distributive property:
Area = x(x + 3) + 7(x + 3)
Area = x^2 + 3x + 7x + 21
Area = x^2 + 10x + 21
Therefore, the area of the rectangle is x^2 + 10x + 21.
Area = (x + 7)(x + 3)
To simplify the expression, you can expand it using the distributive property:
Area = x(x + 3) + 7(x + 3)
Area = x^2 + 3x + 7x + 21
Area = x^2 + 10x + 21
Therefore, the area of the rectangle is x^2 + 10x + 21.
