Question

Evaluate: ab – bc if a = 4, b = 3, and c = 2

ab - bc =

Answer 1

6

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:

`ab - bc \\(4)(3)-(3)(2)\\= 12 - 6 \\= 6`

Therefore, the answer is 6.

Answer 2

(4)(3)-(3)(2) = 12-6 = 6
