Blue
Step-by-step explanation:
I just got this question correct
Answer:
![C(x,y) = (\frac{10}{4},\frac{-1}{4})](https://tex.z-dn.net/?f=C%28x%2Cy%29%20%3D%20%28%5Cfrac%7B10%7D%7B4%7D%2C%5Cfrac%7B-1%7D%7B4%7D%29)
Step-by-step explanation:
Given
![A(x_1,y_1) = (2,-1)](https://tex.z-dn.net/?f=A%28x_1%2Cy_1%29%20%3D%20%282%2C-1%29)
![B(x_2,y_2) = (4,2)](https://tex.z-dn.net/?f=B%28x_2%2Cy_2%29%20%3D%20%284%2C2%29)
Required
Partition = 1:3
Here, we'll make use of the following formula:
![C(x,y) = (\frac{nx_1 + mx_2}{m + n},\frac{ny_1 + my_2}{m + n})](https://tex.z-dn.net/?f=C%28x%2Cy%29%20%3D%20%28%5Cfrac%7Bnx_1%20%2B%20mx_2%7D%7Bm%20%2B%20n%7D%2C%5Cfrac%7Bny_1%20%2B%20my_2%7D%7Bm%20%2B%20n%7D%29)
<em>Where</em>
![m:n = 1:3](https://tex.z-dn.net/?f=m%3An%20%3D%201%3A3)
Substitute values for m,n,x1,x2,y1 and y2
![C(x,y) = (\frac{3 * 2 + 1 * 4}{1 + 3},\frac{3 * -1 + 1 * 2}{1 + 3})](https://tex.z-dn.net/?f=C%28x%2Cy%29%20%3D%20%28%5Cfrac%7B3%20%2A%202%20%2B%201%20%2A%204%7D%7B1%20%2B%203%7D%2C%5Cfrac%7B3%20%2A%20-1%20%2B%201%20%2A%202%7D%7B1%20%2B%203%7D%29)
![C(x,y) = (\frac{10}{4},\frac{-1}{4})](https://tex.z-dn.net/?f=C%28x%2Cy%29%20%3D%20%28%5Cfrac%7B10%7D%7B4%7D%2C%5Cfrac%7B-1%7D%7B4%7D%29)
Answer:
c. ![\frac{3x + 4}{x^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%20%2B%204%7D%7Bx%5E2%7D%20)
Step-by-step explanation:
Given:
![\frac{3}{x} + \frac{4}{x^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7Bx%7D%20%2B%20%5Cfrac%7B4%7D%7Bx%5E2%7D%20)
Required:
The sum
Solution:
![\frac{3}{x} + \frac{4}{x^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7Bx%7D%20%2B%20%5Cfrac%7B4%7D%7Bx%5E2%7D%20)
Common denominator is x².
Therefore, divide x² by the denominator of each fraction and multiply by each of its denominator.
Thus, we would have:
![\frac{3x + 4}{x^2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3x%20%2B%204%7D%7Bx%5E2%7D%20)
Answer:
It should be 136
Step-by-step explanation: I split it up into multiple pieces
Rectangle 1= 20*2=40
Rectangle 2= 14*4=56
Rectangle 3= 20*2=40
40+40+56=136
