The answer is 6/9 or 2/3 because 2X2X2=8 and 9X9X9=729......it equals 8/729
Answer:
5.93 * 10^7
7 represents the amount of times you moved the decimal
Answer:
3/4
Step-by-step explanation:
Because the total homework would be 25/25

15/20 can be reduced to 3/4
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)
