Step-by-step explanation:
Answer:reflections I think
Step-by-step explanation: when you reflect a point across an axis, at least one of the coordinates’ sign will change
If four coordinates are given then:-
- Find length of the sides using distance formula

- Now break down into two triangles .
- Use herons formula and find areas of the triangles .add them and get the area
1. Polynomials are closed under the operations of addition and substraction mean that:
If we add two polynomials, the result is still a polynomial (so still in the set of polynomials)
Also, If we subtract 2 polynomials, the result is a polynomial.
2. Example: given the polynomials :

and

Addition example:


Subtraction example:

=

=

So both M(x)+N(x) and N(x)-M(x) are polynomials
