Factor with GCF and slide and divide 7n^2 + 52n + 21

( 7 n+ 3 )  ( n + 7 )

Step-by-step explanation:

factor by grouping

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
