Answer

17) 35 ### 18) -36 ### 19) -7 ### 20) -19 ### 21) 11 ### 22) 1 Explanation 1. Evaluate Expression 17 5 \cdot 3 - (-5) \cdot 4 = 15 + 20 = 35 2. Evaluate Expression 18 \frac{-12}{-4} \cdot 3 \cdot -4 = 3 \cdot 3 \cdot -4 = -36 3. Evaluate Expression 19 -5 + 3 - (6 - 1) = -5 + 3 - 5 = -7 4. Evaluate Expression 20 -5 + 2 \cdot -4 - 6 = -5 - 8 - 6 = -19 5. Evaluate Expression 21 (-3)^2 - 3 + 5 = 9 - 3 + 5 = 11 6. Evaluate Expression 22 \frac{4 - 1}{-3 + 6} = \frac{3}{3} = 1

Explanation

1. Evaluate Expression 17<br /> $5 \cdot 3 - (-5) \cdot 4 = 15 + 20 = 35$<br /><br />2. Evaluate Expression 18<br /> $\frac{-12}{-4} \cdot 3 \cdot -4 = 3 \cdot 3 \cdot -4 = -36$<br /><br />3. Evaluate Expression 19<br /> $-5 + 3 - (6 - 1) = -5 + 3 - 5 = -7$<br /><br />4. Evaluate Expression 20<br /> $-5 + 2 \cdot -4 - 6 = -5 - 8 - 6 = -19$<br /><br />5. Evaluate Expression 21<br /> $(-3)^2 - 3 + 5 = 9 - 3 + 5 = 11$<br /><br />6. Evaluate Expression 22<br /> $\frac{4 - 1}{-3 + 6} = \frac{3}{3} = 1$
