Factor COMPLETELY the expression 2x^3 - 250
AURORKA [14]

Answer:

2 (x - 5) (x^2 + 5 x + 25)

Step-by-step explanation:

Factor the following:

2 x^3 - 250

Factor 2 out of 2 x^3 - 250:

2 (x^3 - 125)

x^3 - 125 = x^3 - 5^3:

2 (x^3 - 5^3)

Factor the difference of two cubes. x^3 - 5^3 = (x - 5) (x^2 + x 5 + 5^2):

2 (x - 5) (x^2 + 5 x + 5^2)

5^2 = 25:

Answer: 2 (x - 5) (x^2 + 5 x + 25)

The diameter of circle X is 15 centimeters. The diameter of circle Y is 20 centimeters. Which measurement is closest to the diff
valina [46]

The difference between the circumference of circle X and circumference of circle Y is 5π cm.

<h3>What is circumference of a circle?</h3>

This is the distance round a circle.

The circumference of circle X is calculated as follows;

C_X = \pi d\\\\&#10;C_X = 15\pi \ cm

The circumference of circle Y is calculated as follows;

C_Y = \pi d\\\\&#10;C_Y = 20 \pi \ cm

The difference between the circumference of circle X and circumference of circle Y is calculated as follows;

C_Y - C_X = 20\pi - 15 \pi = 5\pi \ cm \\\\&#10;

Thus, the difference between the circumference of circle X and circumference of circle Y is 5π cm.
