Simplify the exponent
-(7)^3

Step-by-step explanation:

Esa sería la respuesta -7×-7×-7=-343

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

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
