To find an expression that has the same sum as \(-15 + 6\), we first calculate the sum:
\[ -15 + 6 = -9 \]
Now, we'll evaluate each of the provided expressions to see which one also sums to \(-9\):
-
\(15 + 6\): \[ 15 + 6 = 21 \]
-
\(-6 + (-15)\): \[ -6 - 15 = -21 \]
-
\(15 + (-6)\): \[ 15 - 6 = 9 \]
-
\(6 + (-15)\): \[ 6 - 15 = -9 \]
The expression \(6 + (-15)\) also sums to \(-9\).
So the correct response is:
6 + (−15).
