18. c. Statement (1) is insufficient because the information does not tell you anything about the individ-ual triangles. Statement (2) gives information about each triangle, but no values for the perimeters.Use both statements and the fact that the ratio of the perimeters of similar triangles is the same as theratio of their corresponding sides. Therefore, 2x+ 3x30. Since this can be solved for x, the perime-ters can be found. Both statements together are sufficient.
