Evaluate the expression 3b−ac when a = 2, b =3, and c=−1.5.

Answer 1

To evaluate the expression 3b − ac when a = 2, b = 3, and c = -1.5, substitute the given values into the expression:

3(3) - (2)(-1.5)

= 9 - (-3)

= 9 + 3

= 12

So, the value of the expression 3b - ac when a = 2, b = 3, and c = -1.5 is 12.
