Answer 2

Simplifying the Expression

To simplify the expression -2.1(3.5 + x - 0.2x) + 1.2(0.3 + x - 0.4x), we can follow the order of operations (PEMDAS/BODMAS) and combine like terms.

1. Simplify the terms inside the parentheses: - 3.5 + x - 0.2x simplifies to 3.5 + 0.8x. - 0.3 + x - 0.4x simplifies to 0.3 + 0.6x.

2. Apply the distributive property: - -2.1(3.5 + x - 0.2x) simplifies to -7.35 - 2.1x + 0.42x. - 1.2(0.3 + x - 0.4x) simplifies to 0.36 + 1.2x - 0.48x.

3. Combine like terms: - -7.35 - 2.1x + 0.42x simplifies to -7.35 - 1.68x. - 0.36 + 1.2x - 0.48x simplifies to 0.36 + 0.72x.

Therefore, the simplified expression is -7.35 - 1.68x + 0.36 + 0.72x.
