Step-by-step explanation:
The answer is D. Hope that helps, so sorry if I'm wrong
composite number means a number that can be formed by multiplying two smaller numbers
3n-1 for n=2, 3n-1=3*2-1=6-1=5
3n-1 for n=10, 3n-1=3*10-1=30-1=29
5 is composite because 2*2.5=5
29 is composite because 5*5.8=29
Answer:
±2 sqrt(3) =x
Step-by-step explanation:
12 - x^2 = 0
Add x^2 to each side
12 - x^2 + x^2 = x^2
12 = x^2
Take the square root of each side
±sqrt(12) = sqrt(x^2)
±sqrt(4*3) = sqrt(x^2)
±sqrt(4) sqrt(3) = x
±2 sqrt(3) =x
Answer: 12 hours
Step-by-step explanation: 6 h = 360 min,9 h = 540 min, 12 h = 720 min
640-360=280 , 640-540=100 , 640-720=-80
