Answer 1

Answer:

13a + 15b + 18

Step-by-step explanation:

5(a + 3b) = 5a + 15b

So the question is: 5a + 15b + 6 + 8a + 12

5a + 8a = 13a

15b stays the same

6 + 12 = 18

So the answer is 13a + 15b + 18

Answer 2

Answer:

13a + 15b + 18

Step-by-step explanation:

5(a + 3b) + 6 + 8a + 12

5a + 15b + 6 + 8a + 12

(5a + 8a) + 15b + (6+12)

13a + 15b + 18
