K
Identify the amount of terms and what the terms are in this expression.
34a + 45a + 21b + 8
4
34a + 45a + 21b + 8
F

18 divided by the sum of k and 6
18/k+6
X
Explain how combining like terms is similar to adding and subtracting whole numbers. How are they different?
It’s the same because you're adding or subtracting numbers but it’s different because they can only be added or subtracted if the variable attached is the same. There are no variables when adding/subtracting regular whole numbers.
