To solve the given expression, we follow the order of operations (parentheses, exponents, multiplication/division, and addition/subtraction). First, we calculate the operations inside the parentheses: 2x3 = 6, and 4:2 = 2. Then, we perform the remaining calculations: 6 + 3x5 - 2 x 2 = 6 + 15 - 4 = 17. Finally, we multiply the result by 2: 17 x 2 = 34. Therefore, the correct answer is 34, not 38.
