What is the solution of |x-4| < 13

- 9 < x < 17

Step-by-step explanation:

An inequality of the type | x | < a , always have a solution of the form

- a < x < a

This can be extended to include expressions in the absolute value, that is

- 13 < x - 4 < 13 ( add 4 to each of the 3 intervals )

- 9 < x > 17

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
