According to my calculations the answer is 69
Answer:
it would be a distance of 7 units
Step-by-step explanation:
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)
Answer:
19/12 or 1 7/12 lbs
5/6 + 3/4
Find a common denominator, aka least common multiple
So, 5/6 becomes 20/24 and 3/4 becomes 18/24
20/24 + 18/24 = 38/24 which simplifies to 19/12 or 1 7/12
