Acompany makes triangular plates for individual slices of pizza. for each plate, the base is 7 inches and the height is 12 inches. the area of the top of the plate is inches squared.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

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

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
