Step-by-step explanation:

ac=0+0 which is 0 so 0 is 0

Answer 2

The sentence that is not true based on the given conditions is ac = bc.

Sentence (s) that is not true

From the given conditions in the question, the sentences that do not follow the condition will not be true.

a = b and c ≠ 0, this implies that c can be any number such as 1, 2, 3, 4.

check ac = bc

let a = b = 1

12 = 21 (12 is not equal to 21)

Thus, the sentence that is not true is ac = bc
