Answer:
This expression was rewritten using the distributive property
5 • (7-1) equals 5 • 6 which equals 30
5 • 7 - 5 • 1 equals 35 - 5 which equals 30
Step-by-step explanation: Distributive property basically says that you can multiply the sum of two or more numbers and you'll get the same answer as you would if you multiplied them separately and then added/subtracted them.
