Final answer:
To solve the expression 5(a + 7) + 2(a + 4), distribute the multiplication over addition, combine like terms, and simplify to get 7a + 43.
Step-by-step explanation:
The question asks to solve the expression 5(a + 7) + 2(a + 4). To find the solution, we need to simplify the expression by distributing the multiplication and combining like terms.
- First, distribute the 5 into (a + 7) to get 5a + 35.
- Next, distribute the 2 into (a + 4) to get 2a + 8.
- Now combine like terms (5a + 2a and 35 + 8) to get 7a + 43.
The simplified expression is 7a + 43. No further simplification can be made without additional information about the value of a.
