Notice that \( 7+(7-3)-1=10 \), but that a different placement of parentheses would yield the statement \( (7+7)-(3-1)=12 \). Place parentheses to turn the equalities below into true statements. (a) \( 13-8-4-1=8 \) (b) \( 13-8-4-1=0 \) (a) Choose the true statement below. A. \( (13-8)-(4-1)=8 \) B. \( 13-8-4-1=8 \) C. \( 13-(8-4)-1=8 \)

We need to determine which placement of parentheses makes the left‐side expression equal to \(8\). Check each option step-by-step: 1. **Option A:** \[ (13-8)-(4-1) \] First, compute: \[ 13-8=5 \quad \text{and} \quad 4-1=3 \] Then subtract: \[ 5-3=2 \] This gives \(2\), not \(8\). 2. **Option B:** \[ 13-8-4-1 \] This expression is evaluated from left to right: \[ 13-8=5, \quad 5-4=1, \quad 1-1=0 \] This gives \(0\), not \(8\). 3. **Option C:** \[ 13-(8-4)-1 \] First, compute the parentheses: \[ 8-4=4 \] Then substitute back into the expression: \[ 13-4-1=8 \] This gives the correct result \(8\). Thus, the true statement is: \[ 13-(8-4)-1=8 \]
