Factor the gcf out of the polynomial 9x^6+6x^4+15x^3
san4es73 [151]

Answer:3x^3(3x^3+2x+5)


Step-by-step explanation:by looking at the polynomial, you can see that all three shares the variable x. Since 9,6, and 25 all share the GCF of 3, you can factor it out. Since the smallest x value of the polynomial is x^3, that is the x value you want to factor out. Since if you factor out x^3 then 15x^3 would not have a variable anymore.

What is the surface area of the cube below? 9 9 9
Natali5045456 [20]

Answer:

A_s=486\ units^2

Step-by-step explanation:

Remember that the sides of a cube always have the same length.

In this case the length of the sides L is:

L = 9.

The cubes have 6 faces. Then the surface area of the cube is equal to the area of its 6 faces.

Since all sides of the cube have the same measure, then the area of each face is:

A = L ^ 2

Then the area of the 6 faces is:

A_s = 6L ^ 2

A_s = 6 * (9 ^ 2)

A_s=486\ units^2
