Answer: x = 6 plus-or-minus 3 StartRoot 10
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 12x + 36 = 90
Rearranging the equation so that it takes the the standard form of
ax² + bx + c, it becomes
x² - 12x + 36 - 90 = 0
x² - 12x - 54 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = - 12
c = - 54
Therefore,
x = [- - 12 ± √(- 12² - 4 × 1 × - 54)]/2 × 1
x = [12 ± √(144 + 216)]/2
x = [12 ± √360]/2
x = (12 ± 6√10)/2
x = 6 + 3√10

Answer:
Step-by-step explanation:
To owe money means you don't have any and borrowed some, or in other words are in debt. Only three of them are in debt, so Simpson doesn't owe anything.
For who owes more, let's start simple. If someone brrowed a dollar from a friend, they are in debt for a dollar. if they borrowed two dollars they suddenly owe more, two dollars instead of one. So Whatever amount of debt is higher tells the highest amoutn owed. Now, what is the highest amount any of the three remaining owe? well, 143 < 178 < 203, so 203 is the highest so Cole owes the most.
