Q. Which expression is equivalent to −5+(−9) ?−9+59−(−5)−5−(−9)−5−9
Calculate −5+(−9): We need to find an expression equivalent to −5+(−9). Let's first perform the calculation for −5+(−9).−5+(−9)=−5−9This simplifies to −14.
Evaluate given options: Now let's evaluate each of the given options to see which one is equivalent to −14.Option 1: −9+5This simplifies to −4, which is not equivalent to −14.
Option 1: Option 2: 9−(−5)This simplifies to 9+5, which is 14. This is not equivalent to −14 because the sign is positive.
Option 2: Option 3: −5−(−9)This simplifies to −5+9, which is 4. This is not equivalent to −14 because the sign is positive.
Option 3: Option 4: −5−9This simplifies to −5−9, which is −14. This is equivalent to the original expression −5+(−9).
