First we will do -3 times everything in the parenthesis.

-3 times -4n = 12n

-3 times 30 = -90

12n = 60

divide 12 on both sides;

n = 5

Which transformations can be used to carry ABCD onto itself? The point of

Answer:

A and B

Step-by-step explanation:

For A, y=2 is the axis of vertical symmetry, meaning a reflection would map the shape onto itself.

For B, x=3 is the axis of horizontal symmetry, meaning a reflection would map the shape onto itself.

For C, a rotation of 90 degrees would make the shape taller vertically and shorter horizontally, therefore it would be wrong.

For D, a translation two units down would move all points down, even though some would need to go up, therefore it would be wrong.
