however, an internal error occurred during the processing of the request. The root cause of this error depends on which module handles the request and what was happening in the worker process when this error occurred.

IIS was not able to process configuration for the Web site or application.
The authenticated user does not have permission to use this DLL.
The request is mapped to a managed handler but the .NET Extensibility Feature is not installed.
Things you can try:
Ensure that the NTFS permissions for the web.config file are correct and allow access to the Web server's machine account.
Check the event logs to see if any additional information was logged.
Verify the permissions for the DLL.
Install the .NET Extensibility feature if the request is mapped to a managed handler.

现在的数学真难呀
不要骗我，我也是这样骗别人的
你采纳谁了
居然是谢谢
只是第9题吗
解析：此题应该先合并同类项化简，然后将a.b的值代入化简后的式子。。解答：原式=2a&#178;b-4a&#178;b+ab&#178;-2ab&#178;=-2a&#178;b-ab&#178;=-（2*（-2）&#178;*2）-（-2*2&#178;）=-16+8=-16

八下数学评价手册第19页第5题怎么写
苏科版：一手机经销商计划购进某品牌的A型、B型、C型三款手机共60部,每款手机至少要购进8部,且恰好用完购机款61000元．设购进A型手机x部,B型手机y部．三款手机的进价和预售价如下表：手机型号 A型 B型 C型进
价（单位：元/部） 900 预售价（单位：元/部） 00（1）用含x,y的式子表示购进C型手机的部数；（2）求出y与x之间的函数关系式；（3）假设所购进手机全部售出,综合考虑各种因素,该手机经销商在购销这批手机过程中需另外支出各种费用共1500元．①求出预估利润P（元）与x（部）的函数关系式；（注：预估利润P＝预售总额-购机款-各种费用）
②求出预估利润的最大值,并写出此时购进三款手机各多少部．（1） 60-x-y
（2）900x+(60-x-y)=61000y=2x-50
（3）①p=y+1300(60-x-y)-
=-100x+300y+15500=-100x+300(2x-50)+1550=500x+500
∴29≤x≤34
∴p随着x的增大而增大
∴p最大值=500×34＋500≡17500
即当x取最大值时,p取最大值
而x可取的最大整数解为34
答：此时购进A型手机34部,B型手机18部,C型手机8部 希望对你有用!
