Answer:
6
Step-by-step explanation:
To evaluate the expression if a = 4, b = 3, and c = 2, substitute those values for the variables and solve. So, substitute 4 for a, 3 for b, and 2 for c, then simplify by the correct order of operations, PEMDAS:
[tex]ab - bc \\(4)(3)-(3)(2)\\= 12 - 6 \\= 6[/tex]
Therefore, the answer is 6.
