Answer:
The answer to your question is 24.7 ft
Step-by-step explanation:
Data
length of the ladder = 25 ft
distance from the ladder to the ladder = 4 ft
distance from the floor to the ladder = ?
Process
1.- Use the Pythagorean theorem to solve this problem
c² = a² + b²
- solve for b
b² = c² - a²
-Substitution
b² = (25)² - (4)²
-Simplification
b² = 625 - 16
b² = 609
-Result
b = 24.67 ft ≈ 24.7 ft
-Conclusion
The ladder is 24.7 ft from the floor.
Answer:
If P represents the population ten years ago, the current population can be expressed as: 2P = 12,000 (or: 2 x 6,000 = 12,000). Over the past ten years, the town's population doubled in size. The population is currently 12,000. Therefore the population ten years ago was 12,000 divided by 2 = 6000.

Step-by-step explanation:
1. Just subtract them. (To subtract easier, ignore the variables and subtract regularly. When you're done go back and put the variables back in)
