Answer: It flies 108 miles in 3 hours.
Step-by-step explanation:
576/16 = 36
It flies 36 miles per hour
36 * 3 = 108
To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.
jk=ac and j+k=b
The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...
2k^2-5k-18=0
2k^2+4k-9k-18=0
2k(k+2)-9(k+2)=0
(2k-9)(k+2)=0
so k=-2 and 9/2
k=(-2, 4.5)
6 goes into 110 approximately 18 times.
The answer is 2 due to the fact that 2 is even, and can be added more than once.
