The polynomial a,b,c,are not perfect square polynomial and the polynomial d is perfect square polynomial.
The given polynomial is

What is the form of perfect square polynomial?

we solve this method by using perfect square method
add and subtract 1/9

factor 36

Now complete the square
Therefore this is not perfect square trinomial.
Similarly for

Complete square is,

This polynomial is also not perfect square trinomial.

complete square is,

This polynomial is not perfect square trinomial.

complete square is,

that should be correct, if not, i apologize T_T
Answer:
The answer is below
Step-by-step explanation:
The question is not complete, no diagram is attached, but I would show how to solve it.
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
If a point A(x, y) is reflected across the x axis, the new point is at A'(x, -y).
If a point A(x, y) is reflected across the y axis, the new point is at A'(-x, y).
If a point A(x, y) is translated a units up and b units right, the new point is at A'(x + a, y + b).
If a point A(x, y) is translated a units down and b units left, the new point is at A'(x - a, y - b).
Answer:
A and B tbh
Step-by-step explanation: there is only 5 prime numbers in 12 and A and B are 6 and 6 a ratio of 6:6
Thus both A and B will be right unless you can pick multiple its A and B
Given:
a.) The price of an item has dropped to $63 today.
b.) Yesterday it was $140.
For us to be able to determine the percentage decrease, we will be using the following formula:

We get,
Original Price = $140
Present Price = $63





Therefore, the decrease of the price in percentage is 55%.
