What is used to show that an assumption is false? a. inductive reasoning b. counterexample c. pattern d. conjecture

It's b.

Step-by-step explanation:

That would be a counterexample.

For example we might conjecture that all numbers of the form n^2 - n + 41 are prime numbers. This is false because of the counterexample if n = 41 then 41^2 - 41 + 41 is divisible by 41.

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
