1. 7(3 + 5) = 21 + 35
2. 15 - 10 = 5 (3 - 2)
You can get these answers by using the distributive property. For example, 7 • 3 is 21 and 7 • 5 is 35, which is why the first answer is valid. I recommend searching up what the distributive property is online if you have anymore trouble with problems like these :)
