[Done] Matt and Karen both attempted to solve the same math problem, but they arrived at different answers. Let's examine their work step-by-step to identify any errors and determine who, if either, is correct. **Matt's Work:** 1. \(6 - 4(3 - 5)^2 + 30 \div 5\) 2. \(6 - 4(-2)^2 + 30 \div 5\) 3. \(6 - 4(4) + 30 \div 5\) 4. \(6 - 16 + 30 \div 5\) 5. \(-10 + 30 \div 5\) 6. \(20 \div 5\) 7. Result: \(4\) **Karen's Work:** 1. \(6 - 4(3 - 5)^2 + 30 \div 5\) 2. \(6 - 4(-2)^2 + 30 \div 5\) 3. \(6 - 4(-4) + 30 \div 5\) 4. \(6 + 16 + 30 \div 5\) 5. \(6 + 16 + 6\) 6. \(22 + 6\) 7. Result: \(28\) **Analysis:** - Both Matt and Karen initially rewrite the expression correctly, substituting \( (3 - 5) \) with \(-2\). - In step 3, Matt calculates \((-2)^2\) as \(4\), which is correct. However, Karen incorrectly calculates \((-2)^2\) as \(-4\). - Matt proceeds with his calculation correctly by multiplying and following the order of operations, but Karen's incorrect calculation in step 3 leads to an incorrect result. **Correct Solution:** 1. Start with \(6 - 4(3 - 5)^2 + 30 \div 5\). 2. Substitute \(3 - 5\) with \(-2\): \(6 - 4(-2)^2 + 30 \div 5\). 3. Calculate \((-2)^2\) as \(4\): \(6 - 4(4) + 30 \div 5\). 4. Multiply: \(6 - 16 + 30 \div 5\). 5. Perform division: \(-10 + 6\). 6. Add to find the result: \(4\). Matt is correct, and the correct answer is \(4\). Karen made an error by calculating \((-2)^2\) incorrectly.
