What is 0.2 [5x + (–0.3)] + (–0.5)(–1.1x + 4.2) simplified?

1.55x - 2.16

Step-by-step explanation:

To simplify the expression, we expand the brackets while taking note of the signs:

0.2 [5x + (–0.3)] + (–0.5)(–1.1x + 4.2)

(0.2 * 5x) + (0.2 * -0.3) + (-0.5 * -1.1x) + (-0.5 * 4.2)

x - 0.06 + 0.55x - 2.1

Collect like terms:

x + 0.55x - 0.06 - 2.1

=> 1.55x - 2.16

This is the simplified expression.

b is the correct answer
