What are the solutions to the equation?
x^3 – 6x^2 – 9x + 54 = 0

x = 6 or x = 3 or x = -3

Step-by-step explanation:

Solve for x over the real numbers:

x^3 - 6 x^2 - 9 x + 54 = 0

Hint: | Factor the left hand side.

The left hand side factors into a product with three terms:

(x - 6) (x - 3) (x + 3) = 0

Hint: | Find the roots of each term in the product separately.

Split into three equations:

x - 6 = 0 or x - 3 = 0 or x + 3 = 0

Hint: | Look at the first equation: Solve for x.

Add 6 to both sides:

x = 6 or x - 3 = 0 or x + 3 = 0

Hint: | Look at the second equation: Solve for x.

Add 3 to both sides:

x = 6 or x = 3 or x + 3 = 0

Hint: | Look at the third equation: Solve for x.

Subtract 3 from both sides:

x = 6 or x = 3 or x = -3

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

the correct answer is d

hope this
