Are (x+10)+x+9 and 2(x+7)+5 Equivalent?
Let's explore whether the expressions (x+10)+x+9 and 2(x+7)+5 are equivalent. To determine this, we need to simplify both expressions and see if they result in the same outcome.
Simplifying the Expressions
1. (x+10)+x+9
- Combine like terms:
- x + x = 2x
- 10 + 9 = 19
- Simplified expression: 2x + 19
2. 2(x+7)+5
- Distribute the 2:
- 2 * x = 2x
- 2 * 7 = 14
- Combine like terms:
- 14 + 5 = 19
- Simplified expression: 2x + 19
Conclusion
After simplifying both expressions, we find that they both result in 2x + 19. Therefore, the expressions (x+10)+x+9 and 2(x+7)+5 are equivalent.
