Answer:
B
Step-by-step explanation:
<em>Let's multiply this out and combine like terms:</em>
![3x(x+1)+x\\=3x^2+3x+x\\=3x^2+4x](https://tex.z-dn.net/?f=3x%28x%2B1%29%2Bx%5C%5C%3D3x%5E2%2B3x%2Bx%5C%5C%3D3x%5E2%2B4x)
So there are 2 terms.
Answer choice B is right.
Given:
A point divides a directed line segment from (-6, -3) to (5,8) into a ratio of 6 to 5.
To find:
The coordinates of that point.
Solution:
Section formula: If point divides a line segment in m:n, then the coordinates of that point are
![Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)](https://tex.z-dn.net/?f=Point%3D%5Cleft%28%5Cdfrac%7Bmx_2%2Bnx_1%7D%7Bm%2Bn%7D%2C%5Cdfrac%7Bmy_2%2Bny_1%7D%7Bm%2Bn%7D%5Cright%29)
A point divides a directed line segment from (-6, -3) to (5,8) into a ratio of 6 to 5. Using section formula, we get
![Point=\left(\dfrac{6(5)+5(-6)}{6+5},\dfrac{6(8)+5(-3)}{6+5}\right)](https://tex.z-dn.net/?f=Point%3D%5Cleft%28%5Cdfrac%7B6%285%29%2B5%28-6%29%7D%7B6%2B5%7D%2C%5Cdfrac%7B6%288%29%2B5%28-3%29%7D%7B6%2B5%7D%5Cright%29)
![Point=\left(\dfrac{30-30}{11},\dfrac{48-15}{11}\right)](https://tex.z-dn.net/?f=Point%3D%5Cleft%28%5Cdfrac%7B30-30%7D%7B11%7D%2C%5Cdfrac%7B48-15%7D%7B11%7D%5Cright%29)
![Point=\left(\dfrac{0}{11},\dfrac{33}{11}\right)](https://tex.z-dn.net/?f=Point%3D%5Cleft%28%5Cdfrac%7B0%7D%7B11%7D%2C%5Cdfrac%7B33%7D%7B11%7D%5Cright%29)
![Point=\left(0,3\right)](https://tex.z-dn.net/?f=Point%3D%5Cleft%280%2C3%5Cright%29)
Therefore, the coordinates of the required point are (0,3).
