Answer:
(3) 2(3x - 5)(3x + 5)
Step-by-step explanation:
![18 {x}^{2} - 50 \\ = 2(9 {x}^{2} - 25) \\ = 2(3x - 5)(3x + 5)](https://tex.z-dn.net/?f=18%20%7Bx%7D%5E%7B2%7D%20%20-%2050%20%5C%5C%20%20%3D%202%289%20%7Bx%7D%5E%7B2%7D%20%20-%2025%29%20%5C%5C%20%20%3D%202%283x%20-%205%29%283x%20%2B%205%29)
Answer:
actually what is this is you is this a geometry, trigonometry I don't know what to call
Given:
The bases of trapezoid measuring 4 m and 12 m.
To find:
The median of the trapezoid.
Solution:
The median of the trapezoid is the average of its bases.
![\text{Median}=\dfrac{\text{Upper base + Lower base}}{2}](https://tex.z-dn.net/?f=%5Ctext%7BMedian%7D%3D%5Cdfrac%7B%5Ctext%7BUpper%20base%20%2B%20Lower%20base%7D%7D%7B2%7D)
The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:
![\text{Median}=\dfrac{4+12}{2}](https://tex.z-dn.net/?f=%5Ctext%7BMedian%7D%3D%5Cdfrac%7B4%2B12%7D%7B2%7D)
![\text{Median}=\dfrac{16}{2}](https://tex.z-dn.net/?f=%5Ctext%7BMedian%7D%3D%5Cdfrac%7B16%7D%7B2%7D)
![\text{Median}=8](https://tex.z-dn.net/?f=%5Ctext%7BMedian%7D%3D8)
Therefore, the correct option is C.
