The regular hexagon abcdef rotates 240º counterclockwise about its center to form hexagon a′b′c′d′e′f′. point c′ of the image coincides with point ? of the preimage. point d′ of the image coincides with point ? of the preimage.

Point C′ of the image coincides with point E of the preimage.

Point D′ of the image coincides with point F of the preimage.

Step-by-step explanation:

A translation counterclockwise 60° moves point A to F, F to E, E to D, et cetera. A translation counterclockwise 180° moves any vertex to the opposite vertex, so A moves to D, B to E, C to F and vice versa. Then, a translation counterclockwise 240° is a combination of the two aforementioned translations and moves A to C, F to B, E to A, D to F, C to E and B to D, creating the hexagon A′B′C′D′E′F′ (see figure attached).

it is x=-4
