Simplify the expression:

Question

7+7(9u+7)

Answer 1

To simplify the expression \( 7 + 7(9u + 7) \), follow these steps:

1. Distribute the \( 7 \) across the terms inside the parentheses: \[ 7(9u + 7) = 7 \cdot 9u + 7 \cdot 7 = 63u + 49 \]

2. Now substitute this back into the expression: \[ 7 + 7(9u + 7) = 7 + 63u + 49 \]

3. Combine the constant terms \( 7 + 49 \): \[ 7 + 49 = 56 \]

4. Therefore, the simplified expression is: \[ 63u + 56 \]

So the final result is: \[ \boxed{63u + 56} \]
