-32x²+8x+24
Answer:
K
Step-by-step explanation:
techincally, I don't know if I am right, but there is more than one answer. The boundries/restrictions of what length DF could be are 2.477 < x < 8.477
Take out the division by bring 5 to the other side. (5x5). then bring the 3 over (-3 turns into +3). then divide by 2 to isolate n. final answer 14.
2n-3= 5x5
2n-3=25
2n=25+3
2n=28
n= 28÷2
n=14
The answer to your problem would be 2Y +3x=6
