demo.java Shapes 2 Shapes Polymorphism Create a set of classes derived from an abstract class Shape, which provides a common interface, for managing various 2D geometric shapes. In our model, each Java object will represent a shape somewhere in a Cartesian coordinate system. However, note that unlike in Mathematics, the positive y-axis grows down from the origin. Shapes All shapes have the following properties: color, area, perimeter, location, and bounds. Shapes are mutable, for example any shape can be moved.
Answer:
The image of truth table is attached.
Explanation:
In the truth table there is a separate table for the expression (A+B).C and for the expression (A.C)+(B.C) you can see in the truth table that the columns of (A+B).C is having same values as the (A.C)+(B.C).Hence we can conclude that (A+B).C is equal to (A.C)+(B.C).

The question is incomplete as there is no link pointing to the houseType struct of chapter 1.
So, I've answered the question from scratch
See attachment for explanation where I used comments to explain each line.
The program is as follows:
#include <iostream>
using namespace std;
struct houseType{
int firstHouse, secondHouse;
};
int main()
{
houseType hT;
cout << "Enter the price of both house: ";
cin>> hT.firstHouse;
cin>> hT.secondHouse;
if(hT.firstHouse == hT.secondHouse){ cout<<"true"; }
else{ cout<<"false"; }
return 0;
}
