Given the point A （20, 25, 30）, point B and point A are symmetric with respect to the V-plane. What are the coordinates of point B（）

There is no point arguing about what _____ the accident. The point is what to do with the victims of it. [ ] The distance from the space point to the horizontal projection plane H can be represented by（）coordinates of the point The distance from the space point to the profile projection plane W can be represented by（）coordinates of the point The melting point of ice and the boiling point of water are the fixed points _____ the Centigrade scale is based. 在OSPF协议中，下列默认属于point-to-point网络的是（） The distance from the space point to the frontal projection plane V is equal to Y coordinate value of the point（） If the degree of financial leverage （DFL） is 1.00, the operating breakeven point compared to the breakeven point, is most likely: 在OSPF协议中，下列默认属于point-to-point网络类型的是（） 在OSPF协议中，下列默认属于point-to-point网络类型的是（） The space point is represented by（） Point out the mistake The point of this flyer is______. Which pattern is used in the following outline when comparison is made？Point 1 Object 1 ➤ Object 2 Point 2 Object 1 ➤ Object 2 Point 3 Object 1 ➤ Object 2（） If you are writing about two equal topics (or are not picking a favorite), consider using a point-by-point outline. Given point A （25, 20, 45） and point B （30, 30, 35）, the relative positions of these two points should be（） 有如下类定义： class Point { int x_,y_; public: Point():x_(0),y_(0){ } Point(int x,int y=0):x_(x),y_(y){} }; 若执行语句 Point a(2),b[3],*c[4]; 则Point类的构造函数被调用的次数是 To a worker,what from the point of view of society is necessary labor is from his own point of view voluntary play. 若有语句int*point,a=4;point=&a;下面均代表地址的一组选项是（） PPP（Point-to-Point Protocol，点到点协议）是一种网络层协议 Space 2: a (10, 12, 20), B (10, 30, 20), indicating that point A is right behind point B.
