To simplify the expression \( -3(u+6)+4 u \), we first distribute the -3: \[ -3u - 18 + 4u \] Next, we combine like terms: \[ (-3u + 4u) - 18 = 1u - 18 \] So the simplified expression is: \[ u - 18 \] Following that, let's do a quick check: If \( u = 0 \), the original expression gives us \( -3(0+6) + 4(0) = -18 \). The simplified form \( 0 - 18 \) also results in -18, confirming that our simplification is correct! \[ \square = u - 18 \] Now you can put that into your table!
