Answer:
72 quarts
Step-by-step explanation:
1 year = 12 months, and Neil changes the oil each month, and each month he uses 6 quarts of oil. So, the number of quarts he will need for a year is
6 + 6 + ... + 6, twelve times, which equals 12(6) = 72 quarts.
The best first step
for the elimination method would be: <span>1. multiply the first equation by 2 and the second equation by 3.
</span><span>
2x - 6y = 2 /*2
5x + 4y = 28 /*3
____________
4x - 12y = 4
15x + 12y = 84
____________
4x - 12y + 15x + 12y = 4 + 84
19x = 88
x = 88/19

It is a scalene obtuse angle because it is greater then 90 degrees and none of the side lengths are equal.
