Mathematics

1. AB \cong CD
congruent means equal

2. AB \cong BC
bisect means to cut a line segment in two equal parts

Above the AB, CD, AB, and BC there has to be a line. I could not write that because LaTeX doesn't allow it.

3. 2x + 5 = 4x-8
You set both equal to each other

4. PA \cong AT
midpoint means that both line segments are equal

Same thing goes for PA, and AT. You need to draw a line above it.

Hope that helped :)

<h3>Answer: Choice C</h3>

======================================================

Explanation:

The x coordinate of the preimage point Q is x = 6.

The x coordinate of the image point Q' is x = 21.

The ratio of image over preimage is 21/6 = (3*7)/(3*2) = 7/2

You'll get this same value if you do the same steps with the y coordinates.

Therefore, the scale factor is 7/2 and the dilation rule is (x,y) \to \left(\frac{7}{2}x, \frac{7}{2}y\right)

Note: 7/2 = 3.5
