Did you just call your kid stuffing ? <| sep |> Fubini ' s Theorem involves a rectangle that it needs to be continuous on . Are you given a rectangle to work with ? <| sep |> Not quite . Problem with E 85 is that there ' s no alternatives for those of us whose equipment is being damaged by it . For example , older automobiles are incurring hidden damage from E 85 because their gas tanks are now rusting from the inside out . and sure , we can simply try to ignore this because they ' re old cars , but that ' s still damage above beyond routinely accepted wear and tear which hurts the consumer with higher maintenance costs and lower residual values . That ' s a cost displacement that benefits a few Corn growers while screwing over older car owners . And it is particularly disconcerting to be lucky enough to own an old collectible car to know that it ' s gas tank is rusting from the inside out . and there ' s not a damn thing you can reasonably do about it because you can ' t locally find nonEthanol laced gas at any price FYI , this varies by region , and that it is going to cost you $ 2 K for a new gas tank when the current one rots through . Hopefully , I ' ll detect the inevitable fuel leak before it burns down my garage house and kills my family . But golly , the fat cats at ADM Big Agriculture are laughing their way to their bank with the extra fuel expense I have to pay because Congress said so . hh
