Answer 2

To simplify the expression, let's perform the calculations step by step:

Given expression: 0.8x + 1.2(7.4 - 4)

Step 1: Calculate the value inside the parentheses: 7.4 - 4 = 3.4

Step 2: Multiply the value inside the parentheses by 1.2: 1.2 * 3.4 = 4.08

Step 3: Multiply 0.8 by x: 0.8x

Step 4: Add the results from Steps 2 and 3: 0.8x + 4.08

So, the simplified expression is 0.8x + 4.08.
