Last question on my assignment and i have no idea how to do it! i really need .

310

Step-by-step explanation:

divide this figure into two rectangles, one with length of 3x-7 and width of x, the other one with length of 2x and 5x+2. plug x=5 into these, the first rectangle's area is 5*8=40, the second rectangle's area is 10*27=270. 40+270=310

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
