Answer:
The factors of given expression are 10+10√2 and 10-10√2.
Step-by-step explanation:
We have given a quadratic expression.
s²-20s-100
We have to find factors of given expression.
We use quadratic formula to find factors.
x = (-b±√b²-4ac) / 2a
From given expression, a = 1 , b = -20 and c = -100
Putting values in above formula, we have
x = (-(-20)±√(-20)²-4(1)(-100) ) / 2(1)
x = (20±√400+400 ) / 2
x = (20±√800) / 2
x = (20± √400×2) / 2
x = (20±20√2) / 2
x = 10±10√2
Hence, the factors of given expression are 10+10√2 and 10-10√2.

Answer:
$433.84
Step-by-step explanation:
First, find the amount of money Jennifer earned for regular work time:
8.50 x 43 = 365.50
Then, find the amount of money Jennifer earned for overtime work:
10.50 x 6.5 = 68.25
Finally, add them:
365.50 + 68.25 = 433.75
