Final answer:
When a = -4, b = 5, and c = -2, the value of the expression 4b - 2c is 24.
Step-by-step explanation:
In this case, a = -4, b = 5, and c = -2. Substituting the values into the expression 4b - 2c, we get:
4(5) - 2(-2) = 20 + 4 = 24.
Therefore, the value of the expression 4b - 2c when a = -4, b = 5, and c = -2 is 24.
