Answer:
n=30
Step-by-step explanation:
4 15
------ = --------
8 n
using cross products
4n = 8*15
4n = 120
divide by 4
4n/4 =120/4
n = 30
Answer:
The equation of the line segment between points A and X is
![sA + (1-s)X, s\in[0,1]](https://tex.z-dn.net/?f=sA%20%2B%20%281-s%29X%2C%20s%5Cin%5B0%2C1%5D)
Then we need that the point C satisfy:
.
This implies that

We replace the value of s in the equation we get from the second component

Then the point
lies on the line through A and X.
Answer:
7x² + 11x - 18
Step-by-step explanation:
13x² - 8 + 11x - 6x² - 10
13x² - 6x² + 11x - 8 - 10
7x² + 11x - 18
