Which answer best describes the solution for x if – 3 < x + 4 ≤ 7? a. x > –7 b. x > –7 and x < 3 c. x ≥ –7 and x ≤ 3 d. x > –7 and x ≤ 3

The answer would be D. In order to solve this, you need to first get x by itself. To do this we would subtract both sides by 4. This would then give us our answer of -7< x  ≤ 3

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
