Here's how to simplify the expression for question 57: Step 1: Distribute the numbers outside the parentheses. 5(3a - 2b) - 2(a + 4b) = (5 × 3a) - (5 × 2b) - (2 × a) - (2 × 4b) = 15a - 10b - 2a - 8b Step 2: Combine like terms (a terms with a terms, and b terms with b terms). = (15a - 2a) + (-10b - 8b) = 13a - 18b The simplified expression is 13a - 18b. Comparing this to the given options: (A) 13a - 18b (B) 15a - 10b (C) 13a - 2b (D) 3a - 6b The correct option is (A). The final answer is A. Send me the next one 📸
