Answer:
A, D, & F
Explanation:
When you distribute, you get 6a + 5a + 5 - 3a + 21.
After combining like terms, you get 8a + 26.
Lastly, all you have to do is figure out which expressions are equivalent to
8a + 26.
A) 8a + 26 = 8a + 26
D) 6a + 5a + 5 - 3a + 21 (combine like terms) = 8a + 26
F) 2(4a + 13) - Simple distribution
2 x 4a = 8a
2 x 13 = 26
2(4a + 13) = 8a + 26
