Answer 2

To find the value of the expression -4a·b+12 given that a = 3 and b = -4, we just need to substitute the values of a and b into the expression and perform the calculations.

First, let's substitute the values:

-4a·b+12 = -4(3)(-4) + 12

Next, perform the calculations:

-4a·b+12 = -4(-12) + 12

-4a·b+12 = 48 + 12

-4a·b+12 = 60

So, the value of the expression -4a·b+12 when a = 3 and b = -4 is 60.
