Ok, so here your being asked to solve 6x2<span> + 5x = -7
The procedure that I did was using this formula it led me to get the following:
</span>Using the formula:
x = -(-5) ± √(-5)² - 4(6)(-6)/ 2(6)
x = 5 ± √ 25 + 144 / 12
x = 5 ± √ 169 / 12
x = 5 ± 13/12
x1 = 5 + 13/12
x1 = 18/12
x1 = 3/2
x2 = 5 - 13/12
x2 = -8/12
<span>
x2 = - 2/3
Hope this helped :)</span>

Step-by-step explanation:









Hope this helps!
It has been given in the question that Mary's team had lost 30% of the total of 20 games. There has been no ties for this team. It is required to find the number of matches that Mary's team lost.
Total number of games played = 20
Percentage of games lost by Mary's team = 30%
Number of games lost by Mary's team = (30/100) * 20
= 3 * 2
= 6
So Mary's team lost 6 games in all. I hope this is the answer you were looking for. The process is easy once you understand the words of the problem.
