Final answer:
To simplify the expression 1.2(20+0.5) using the distributive property, multiply 1.2 by both numbers separately, and then add the results. The simplified form is 24.6.
Step-by-step explanation:
To simplify the expression 1.2(20+0.5) using the distributive property, we need to multiply 1.2 by both 20 and 0.5 separately, and then add the results.
1.2(20+0.5) = 1.2(20) + 1.2(0.5)
Now, we can calculate:
1.2(20) = 24
1.2(0.5) = 0.6
Therefore, 1.2(20+0.5) simplifies to 24 + 0.6 = 24.6
