2x ≥ 6
Isolate the x. Divide 2 from both sides
2x/2 ≥ 6/2
x ≥ 6/2
x ≥ 3
x ≥ 3 is your answer

So after every 2 hours the bacteria's numbers double (or 100% is "added") so we can simplify 12 down to 6 because we only want the number after every two hours, 400+800+1600+3200+ 6400+ 12800 = 25200 total after 12 hours
Answer:
57,900 cm³ (3 sf)
Step-by-step explanation:
Volume = (4/3)×pi×r³
= (4/3)×pi×24³
= 57,905.835790966 cm³
= 57,900 cm³ (3 sf)
