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 equivalence, we need to simplify both expressions and see if they result in the same outcome.
Simplifying the Expressions
Expression 1: (x+10)+x+9
- Remove parentheses: x + 10 + x + 9
- Combine like terms: 2x + 19
Expression 2: 2(x+7)+5
- Distribute the 2: 2x + 14 + 5
- Combine like terms: 2x + 19
The Verdict
After simplification, we see that both expressions result in 2x + 19.
Therefore, (x+10)+x+9 and 2(x+7)+5 are indeed equivalent expressions.
This means that no matter what value you substitute for 'x', both expressions will produce the same result.
