The correct Answer is:
To solve the expression \((69 - 14 \times 3 + 2) / (9 \times 5 - (5)^2)\), we will follow these steps: ### Step 1: Simplify the Numerator The numerator is \(69 - 14 \times 3 + 2\). 1. Calculate \(14 \times 3\): \[ 14 \times 3 = 42 \] 2. Substitute back into the numerator: \[ 69 - 42 + 2 \] 3. Perform the subtraction and addition: \[ 69 - 42 = 27 \] \[ 27 + 2 = 29 \] So, the numerator simplifies to \(29\). ### Step 2: Simplify the Denominator The denominator is \(9 \times 5 - (5)^2\). 1. Calculate \(9 \times 5\): \[ 9 \times 5 = 45 \] 2. Calculate \((5)^2\): \[ (5)^2 = 25 \] 3. Substitute back into the denominator: \[ 45 - 25 \] 4. Perform the subtraction: \[ 45 - 25 = 20 \] So, the denominator simplifies to \(20\). ### Step 3: Divide the Numerator by the Denominator Now we have: \[ \frac{29}{20} \] ### Final Result The simplified expression is: \[ \frac{29}{20} \]
