Answer 3

To evaluate the expression "Ab + 3c" with the given values, substitute the values of a, b, and c into the expression:

a = 1/7 b = 14 c = -2

Now, plug these values into the expression:

Ab + 3c = (1/7 * 14) + (3 * -2)

Now, perform the calculations:

Ab + 3c = (2) + (-6) = -4

So, "Ab + 3c" evaluates to -4 with the given values.
