C. Solve the following problems by detfuction:
1. Use deductive reasoning to show that the folawing produces always the number 3.
Pick a number. Add 5 to it. Subitract 7 from the result. Subtract twice the original
number from the previous result.
2. Use deductive reasoning to show that the following produces always the original number

3. The nth term formula for the maximum number of pieces of baked cheese cake, P that can
be produced by n straight cuts is P,=
a. Use the nth term formula to determine the maximum number of pieces that can be
n(n+1)
produced by 7 straight cuts.
b. What is the smallest number of straight cuts that you can use if one wishes to
produce at least 45 pieces?
