−2ab + 14ab + 5

Answer 1

To simplify the expression \( 2a - 4b + 7 + 8a + 6b - 2 \), let's combine like terms.

1. Combine the \(a\) terms: \[ 2a + 8a = 10a \]

2. Combine the \(b\) terms: \[ -4b + 6b = 2b \]

3. Combine the constant terms: \[ 7 - 2 = 5 \]

Putting it all together, we have: \[ 10a + 2b + 5 \]

So the simplified expression is: 10a + 2b + 5.

The correct response is: 10 a plus 2 b plus 5.
