**Warm-Up** (*Give students 5 minutes, then show answers. Note: √ will mean “square root”. On this website, I can’t get the top part of the square root sign. So square root of 16 will look like this: √16)*

Solve each:

1.) √49

2.) √25•√4

3.) √(8•2)

4.) Dilate A(-5,2) by a scale factor of 1/4 with center P(7, -6).

Answers:

- 7 2. 5•2 = 10 3. √16 = 4 4. (-5, 2)-> (-12, 8) -> (-3, 2) -> A'(4, -4)

*Now show the following video*:

Pass out the Simplifying Radicals WS. (Simplifying Radicals) Give students 5 minutes to begin work (they don’t have to finish it now), then show the next video:

Students have the rest of the period to complete their yellow geometric mean WS that was passed out Wed/Thurs.
