Factor the expression by taking out the GCF. 3x - 9x3

Mathematics
1 answer:
Sholpan [36]3 years ago
4 0

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.
