First, distribute the 7: $7x + 49y$. Then distribute the 2: $8x + 16y$. Combine like terms: $7x + 8x = 15x$ and $49y + 16y = 65y$. Thus, the expression simplifies to $15x + 65y$.

Remove the Parentheses by Multiplying and Then Simplify by Combining 7(x+7y)+2(4x+8y)7 ( x + 7 y ) + 2 ( 4 x + 8 y )7(x+7y)+2(4x+8y)
