The area of triangle M'N'O' is 49x square units.
This is because when a figure is dilated by a scale factor of 7, the area is scaled by the square of the scale factor. In this case, the scale factor is 7, so the area is scaled by 7^2, which is 49. Multiplying 49 by x gives the area of triangle M'N'O'.
Therefore, the correct answer is B. (7)^2x square units.
Triangle MNO is dilated by a scale factor of 7 to create triangle M'N'O'.

This statement is not true because the given transformation (x, y) → (x + 5, y + 3) shifts each point of the original pentagon 5 units to the right and 3 units up. This means that each side length of the transformed pentagon N'P'Q'R'S' will be greater than the corresponding side length of the original pentagon NPQRS.
