So,
You have to undistribute a common factor in all of the terms.
2a + 2b
There is a 2 in each term.
Undistribute.
2(a + b)
For this case we have the following product:

We must use the distributive property correctly to solve the problem.
We have then:

Then, we must add similar terms.
We have then:
Answer:
The final product is given by:
option 2
Solution: The commutative property of addition states that when two numbers are being added, their order can be changed without affecting the sum.
Sum = ADDITION SO ... 11 + 12 = 23.
