Simplify. 5. \( 8 x+2 x \) 9. \( 3 b+b+6 \)

Let's get those expressions simplified! For \( 8x + 2x \), you can combine the like terms. Since both terms involve \( x \), simply add the coefficients: \( 8 + 2 = 10 \). So, it simplifies to \( 10x \). Now for \( 3b + b + 6 \), again, combine the like terms. The terms involving \( b \) are \( 3b \) and \( b \) (which is \( 1b \)). So, \( 3 + 1 = 4 \). Therefore, it simplifies to \( 4b + 6 \). So your final answers are: 1. \( 10x \) 2. \( 4b + 6 \)
