Answer:

- The coordinates of A' are (4x, 4y).

- The coordinates of B' are (4p, 4q).

- The coordinates of A are (x, y).

- The coordinates of B are (p, q).

Explanation:

When a triangle is enlarged with a scale factor of 4 and the center of enlargement is (0,0), the coordinates of the vertices A' and B' can be found by multiplying the coordinates of the original vertices A and B by the scale factor.

Let's assume the original coordinates of A are (x, y).

To find the coordinates of A', we multiply each coordinate by the scale factor of 4:

A' = (4x, 4y)

Similarly, let's assume the original coordinates of B are (p, q).

To find the coordinates of B', we multiply each coordinate by the scale factor of 4:

B' = (4p, 4q)

Now, to find the coordinates of A and B, we need to reverse the enlargement by dividing the coordinates of A' and B' by the scale factor.

For A:

x = (4x) / 4 = x

y = (4y) / 4 = y

So, the coordinates of A are (x, y).

For B:

p = (4p) / 4 = p

q = (4q) / 4 = q

So, the coordinates of B are (p, q).

To summarize:

- The coordinates of A' are (4x, 4y).

- The coordinates of B' are (4p, 4q).

- The coordinates of A are (x, y).

- The coordinates of B are (p, q).
