Final answer:

Shape A is enlarged with a scale factor of 2 and center (-3, -5) by multiplying the coordinates by the scale factor, subtracting the center coordinates, and listing the new coordinates.

Step-by-step explanation:

To enlarge shape A with a scale factor of 2 and center (-3, -5), we need to apply the scale factor to each coordinate of shape A and then shift the coordinates by (-3, -5). Here are the steps:

  1. Multiply each x-coordinate of shape A by 2 and subtract 3.
  2. Multiply each y-coordinate of shape A by 2 and subtract 5.
  3. List the new coordinates.

Let's apply these steps to shape A:

  1. Original coordinate: (-1, -7)
  2. After scaling: (-1*2-3, -7*2-5) = (-5, -19)
  3. After shifting: (-5+(-3), -19+(-5)) = (-8, -24)
  4. So the first coordinate is (-8, -24).
  5. Repeat these steps for the other coordinates.
  6. The other coordinates are (-1, -3), (-5, -3), and (-5, -7).

Therefore, the correct answer is A) (-8, -24), (-1, -3), (-5, -3), (-5, -7).
