Determine whether each sentence is a correct application of the distributive property.justify your answer
1. 3(7+9)=3(7)+3(9)
2. -5+(10+2)= -5(10)+ -5(2)
3. [12(3)-8(3)]=(12-8) (3)
4. -4(½ +⅓) = -4 +½+⅓
5. 16(2.5) = 16(2) + 16(0.5)
1. 3(7+9)=3(7)+3(9)
2. -5+(10+2)= -5(10)+ -5(2)
3. [12(3)-8(3)]=(12-8) (3)
4. -4(½ +⅓) = -4 +½+⅓
5. 16(2.5) = 16(2) + 16(0.5)
