ƒ(x) = 5x^2 − 9x + 18,

45 - 27+18

Answer:
56 + 5xx < 65
xx < 1.8
Step-by-step explanation:
56 + 5xx < 65
subtract 56 on both sides
56 + 5xx < 65
-56 -56
5xx < 9
divide by 5 on both sides
5xx/5 < 9/5
xx < 1.8 gigabytes
Answer:
30 days
Step-by-step explanation:
3/10 is completed in 9 days, so 6/10 in 18 days and 9/10 in 27 days.
If it only takes 9 days for 3/10, then 9 divided by 3 = 3. The final 1/10 is completed in 3 days. This all equals 30 days.
I could be wrong, but that's what I think.
