Answer:
Distributive Property
Step-by-step explanation:
can be simplified to by adding the 7 and 10 to get
.
cannot be simplified any more by combining like terms.
By distributing the 2b into the parentheses, you can simplify the expression:
Here you can just add:
Thus, the only expression that cannot simplify any more using adding like terms is the second,
.
