Consider the expression $3x-9x^3.$ It consists of two terms:

$3x=3\cdot x$

and

$-9x^3=-3\cdot 3\cdot x\cdot x\cdot x.$

The common factors in these terms are $3$ and $x.$ Then

$GCF(3x,-9x^3)=3x.$

Taking out the GCF, you obtain

$3x-9x^3=3x(1-3x^2).$

Answer: correct choice is B.

On a coordinate plane, a circle has a center at (negative 2, 0). Point (negative 2, 4) lies on the circle.

wlad13 [49]

The correct answer to where the point(1, StartRoot 7 EndRoot) lies on the circle is A. Yes, the distance from (–2, 0) to (1, StartRoot 7 EndRoot) is 4 units

<h3>What is a Coordinate Plane?</h3>

This refers to the tool that is used to graph points on a two-dimensional plane that intersects two number lines.

Hence, given the information in the given diagram, there is a coordinate plane that shows a circle at the center that has certain values on the y and x-axis.

We can state that the point (1, StartRoot 7 EndRoot) lies on the circle shown because the distance from (–2, 0) to (1, StartRoot 7 EndRoot) is 4 units.
