Answer:
D) -5x(x² + 2x + 3)
Step-by-step explanation:
-5x³ - 10x² - 15x
Common factor:
-5x
Factored:
-5x(x² + 2x + 3)
-14.13
hopefully i’m right
You just need pythagorean theorem c=a2+b2=72+42≈8.06226
Answer:
<em>number = 0.011</em>
Step-by-step explanation:
<u>Decimal Representation</u>
The model is shown in the figure. It has a form of a cube where each face is divided into 10 equal squares, forming a 10x10x10=1,000 smaller cubes piece.
Out of that 1,000 cubes, only 11 are shaded. This leaves us to think the decimal represented by the model is the division between the shaded cubes by the total cubes, thus:

Dividing:
number = 0.011
Answer: Each time the pentagon is rotated , it maps back onto itself. There are five values of for which the pentagon maps back onto itself. This is the same as the number of sides of the pentagon.
