<h3>
Answer: Rhombus and square</h3>
Explanation:
Any rhombus has its diagonals meet at 90 degree angles. The proof for this is a bit lengthy, so I'll let you handle it. The basic idea is to draw in the diagonals, which forms smaller triangles. Proving those triangles to be congruent leads to supplementary congruent angles, which in turn leads to the 90 degree angles needed.
A square is a special type of rhombus where all four angles are the same (each 90 degrees). Put another way, a square is both a rectangle and a rhombus at the same time.
Some rectangles are not squares, so the non-square rectangles will have the diagonals not be perpendicular.
Answer:
For 
, Leading coefficient is -2, Degree is 2, Constant term is 0
For 
, Leading coefficient is -25, Degree is 2, Constant term is 9
For 
, Leading coefficient is 1, Degree is 5, Constant term is -1
Step-by-step explanation:
Given:
Polynomials:
To find: leading coefficient, constant term and degree
Solution:
Leading coefficient is the coefficient of the variable with the highest power.
Degree is the highest power of the variable.
The term of degree 0 is the constant term of a polynomial.
For ,
Leading coefficient is -2
Degree is 2
Constant term is 0
For
Leading coefficient is -25
Degree is 2
Constant term is 9
For
Leading coefficient is 1
Degree is 5
Constant term is -1
Write 3 four times and multiple them together. Then, write out 5 two times and multiple it together. Whatever those two answers are, subtract them
It is equivalent because of the distributive property. If you multiply 4 by x and y, you get 4x and 4y.
4x + 4y = 4x + 4y
