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:
The answer is A. $421.29
Step-by-step explanation:
Just keep finding 19% of the numbers next, and you add that all up and you get the answer.
250 x 19%=47.5. (250+47.5)=> 297.5x19%= 56.525. (297.5+56.525) =>354.025x19%=67.26475
354.025+67.26475=> 421.28975, which can round up to 421.29.
I pretty sure the best answer would be f(x)=cbrt(27-x)
cbrt means cube root by the way.
