A correct answer can only be obtained from a complete question.
A rotation is not always about the origin, but in the absence of information, this will be assumed.
Rotating to the right is assumed to mean rotated from the second towards the first quadrant about the origin.
Rotating any shape about the <em>origin</em> by 360° will always return to the original (starting) position, so the final coordinates will be (-8,2) (-8,8) (-4,2).
-2/5n=-30n multiply both sides by -1 sinc I don' like negatives 2/5n=30n multipl yboth sides by 5/2 1n=150/2n n=75n this is obviously false, the only number that would work is 0 since 0 =0 times 75
