Answer:
9. 6k + 5 and 2k - 1.
10. 5√2 .
Step-by-step explanation:
9. Area = 12k^2 + 4k - 5
Factoring:
12k^2 - 6k + 10k - 5
= 6k(2k - 1) + 5(2k - 1)
= (6k + 5)(2k - 1)
So the required lengths are 6k + 5 and 2k - 1.
10. The ratio of a leg to the hypotenuse is 1: √2 so if the hypotenus = 10 the length of a leg is 10 / √2
= 10 √2 / 2
= 5√2 .

Answer: 510 flights
Step-by-step explanation:
85% are expected to arrive on time, so we can convert that to a decimal, which is 0.85. (To convert a percentage to a decimal we can divide by 100.)
After this we take the TOTAL AMOUNT OF FLIGHTS x 0.85
Total Amount = 600
600 x 0.85 = 510.
