Below is the diagram for help.
Step-by-step explanation:
We are given with an already constructed circle of diameter and
as radius.
To draw a regular hexagon(six-sided), we need to make first cut on the circle of an arc equal to radius of the circle taking any point of the diameter as center
So here, We will consider as a center and take an arc of length
and make a cut on the circle.
This would be the first step and James need to repeat the same steps by considering the newly formed cut as center each time.
Complete Question: Which of the following is an example of the difference of two squares?
A x² − 9
B x³ − 9
C (x + 9)²
D (x − 9)²
Answer:
A. .
Step-by-step explanation:
An easy way to spot an expression that is a difference of two squares is to note that the first term and the second term in the expression are both perfect squares. Both terms usually have the negative sign between them.
Thus, difference of two squares takes the following form: .
a² and b² are perfect squares. Expanding will give us
.
Therefore, an example of the difference of two squares, from the given options, is .
can be factorised as
.
