Module I
1. Given the following formulas: If Q = 2310, π = 22/7, and a = 21, find the value of P.
| Q = πad | m = d2 - a2 | P = 1/3 πa 2m |
2. Two students write the following expressions to answer an exercise:
| 7 + 4(5 - 3)2 + 9/3 | 9/3 + (5 - 3) 2 x 4 + 7 |
a. Simplify the two expressions. List each step you use (attach work).
b. Explain the similarities in the steps (attach work).
c. Make up another expression that uses the same numbers and operations but has a different answer. Then simplify, listing each step.
