Answer:
D 24
Step-by-step explanation:
So 48 and (3x+12) are congruent by Alternate Exterior Angles, so all you need to do is equal them to each other and solve.
Firstly, subtract 12 on each side:
Then divide both sides by 3, and your answer should be , or B.

Answer: Choice A. (-2,1)</h3>
Explanation:
The notation means we apply the dilation to some point (x,y) to move it to . Each coordinate has been multiplied by 4 which is the scale factor. This only works when we center the dilation around the origin. The "O" in refers to "origin". It's not the number zero.
So to go from preimage to image, we multiply by 4. To go in reverse, we divide by 4.
G' is at (-8,4). Divide each coordinate by 4 to get (-2,1) which is where point G is located.
Add the two numbers 3004000000+2749000000 and divide by 2
which equals 2876500000 or 2.8765x10^9
