A cone that is sliced through the vertex would make the shape of a triangle.
You are told the h eight is 10 cm and the radius is 4 cm.
The radius would be half the base, so the base would be 4 * 2 =8 cm.
The area of the triangle is found by multiplying the base by the height, then dividing by two.
Area = 8 x 10 = 80
80 / 2 = 40 square centimeters.
Answer: ![x(x-2)](https://tex.z-dn.net/?f=x%28x-2%29)
Step-by-step explanation:
We have the following expression:
![-x^2 + 2x](https://tex.z-dn.net/?f=-x%5E2%20%2B%202x)
Which can also be written as:
![2x-x^2](https://tex.z-dn.net/?f=2x-x%5E2)
Here, the common factor is
. Hence, if we apply this common factor we will have:
![2x-x^2=x(2-x)](https://tex.z-dn.net/?f=2x-x%5E2%3Dx%282-x%29)
Then, the factored form is: ![x(2-x)](https://tex.z-dn.net/?f=x%282-x%29)
