Final answer:
To simplify 15x13 + 15x17 using the distributive law, distribute 15 to both terms and then combine the results.
Step-by-step explanation:
To simplify the expression 15x13 + 15x17 using the distributive law, we need to distribute the 15 to both terms inside the parentheses. This means multiplying 15 by 13 and 15 by 17 individually:
15x13 = 195
15x17 = 255
Then, we can combine the results:
195 + 255 = 450
Therefore, the simplified expression is 450.
