Answer:
1.55x - 2.16
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.
