1. Distribute the 3 into (2p + 5) to get 6p + 15.
2. Distribute the -4 into (p + 3) to get -4p - 12.
3. Combine like terms: 6p - 4p gives 2p and 15 - 12 gives 3.
4. The final expression is 2p + 3.

QUESTION l. An investigation has been carried out in a region to know the perception of "citizen insecurity" of its inhabitants. 1,270 people in the region were interviewed, of which 27.1% responded that it was a "serious" problem.
