1. The points P, Q, R are 3 points in a plane, the distance PQ is 15 and distance QR is 10.
Col A: Distance between points P & R.
Col B: 20

2. If |x-2| = 6, then
Col A4-x)2
Col B4+x)2

3. If x < 0, then
Col A: |x| + |-2|

4. In a college, 60% of all sophomores have liberal studies as their major subject, 24% of all sophomores have social history as their major and the rest have other subjects or have not yet chosen a major.

Col A: Area of the triangle ABC
Col B: 24

2. Were supposed to guess the relationship? Greater Than, Less Than, Equal to, or Cannot Be Determined?

1)

1a) Draw a circle.
1b) Place Q at the center.
1c) Place R somewhere on the circle.
1d) Draw a line segment QR and label it 10.
1e) Draw another circle bigger than the first one.
1f) Place P somewhere on the larger circle.
1g) Draw a line segment QP and label it 15.
1h) IN YOUR MIND, move P and R around their respective circles.

Can you find the minimum and maximum distance between P and R?
What if they go opposite directions?
What if they go the same direction?

Note: You can use your fingers to move P & R around, but that takes longer. You're in the GRE! You need speed!
