Answer:
First write the polynomial
![\qquad\quad {:}\longrightarrow\sf 7-x (2x+1)](https://tex.z-dn.net/?f=%5Cqquad%5Cquad%20%7B%3A%7D%5Clongrightarrow%5Csf%20%207-x%20%282x%2B1%29)
![\qquad\quad {:}\longrightarrow\sf 7-2x^3-x](https://tex.z-dn.net/?f=%5Cqquad%5Cquad%20%7B%3A%7D%5Clongrightarrow%5Csf%20%207-2x%5E3-x%20)
- Substitute the value of x=-5
![\qquad\quad {:}\longrightarrow\sf 7-2 (-5)^3- (-5)](https://tex.z-dn.net/?f=%5Cqquad%5Cquad%20%7B%3A%7D%5Clongrightarrow%5Csf%20%207-2%20%28-5%29%5E3-%20%28-5%29)
![\qquad\quad {:}\longrightarrow\sf 7-250 +5](https://tex.z-dn.net/?f=%5Cqquad%5Cquad%20%7B%3A%7D%5Clongrightarrow%5Csf%20%207-250%20%2B5%20)
![\qquad\quad {:}\longrightarrow\sf -238](https://tex.z-dn.net/?f=%5Cqquad%5Cquad%20%7B%3A%7D%5Clongrightarrow%5Csf%20%20-238%20)
U do the same steps add the numbers together and then divide them by how many numbers are there and therein ur answer
Answer:
There are 177,100 ways.
Step-by-step explanation:
Since there is no regard to order, we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
![C_{n,x} = \frac{n!}{x!(n-x)!}](https://tex.z-dn.net/?f=C_%7Bn%2Cx%7D%20%3D%20%5Cfrac%7Bn%21%7D%7Bx%21%28n-x%29%21%7D)
In this question:
6 keyboards from a set of 25. So
![C_{25,6} = \frac{25!}{6!(25-6)!} = 177100](https://tex.z-dn.net/?f=C_%7B25%2C6%7D%20%3D%20%5Cfrac%7B25%21%7D%7B6%21%2825-6%29%21%7D%20%3D%20177100)
There are 177,100 ways.
Answer:
5![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
Step-by-step explanation:
This is a special right triangle, the side length that sees 30 degrees is equal to 5 then the side length that sees 90 degrees is 10 and the side length that sees angle measure 60 degrees is 5![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
A cube has equal sides if they are 2÷ 1/2 each then L×W×H would be (2÷ 1/2)^3. To divide fractions we multiply the reciprocal.
2÷ 1/2 = 2/1 × 2/1 = 4
4×4 = 16×4= 64
answer is V = 64 inches cubed.
