To evaluate the expression when a=4, b=-5, and c=-8, we simply substitute the given values of a, b, and c into the expression.
Let's say our expression is: E = 3a - 2b + c
Now, substitute the values:
E = 3(4) - 2(-5) + (-8)
First, multiply 3 by 4:
E = 12 - 2(-5) + (-8)
Next, simplify the multiplication:
E = 12 + 10 + (-8)
Then, perform addition and subtraction:
E = 22 + (-8)
Finally, calculate:
E = 14
Therefore, when a=4, b=-5, and c=-8, the value of the expression E = 14.
