Answer: $7,018,000</h3>
This value is a little over 7 million dollars
======================================================
Explanation:
120,587 rounds to 121,000 when rounding to the nearest thousand.
The instructions don't mention rounding 58, so we'll leave it as that
Multiply the values to get
58*121,000 = 7,018,000
which is the estimate of how much money was earned.
-----------
The actual amount of money earned is
58*120,587 = 6,994,046
which isn't too far off of our estimate.
-----------
Note: the value of 25 days is never used. You could have any other number of days you want, and the answer is still the same. This value is probably either filler or some kind of distraction.

Step-by-step explanation:
Answer:
x = - 1 ± 2i
Step-by-step explanation:
we can use the discriminant b² - 4ac to determine the nature of the roots
• If b² - 4ac > , roots are real and distinct
• If b² - 4ac = 0, roots are real and equal
• If b² - ac < 0, roots are not real
for x² + 2x + 5 = 0
with a = 1, b = 2 and c = 5, then
b² - 4ac = 2² - (4 × 1 × 5 ) = 4 - 20 = - 16
since b² - 4ac < 0 there are 2 complex roots
using the quadratic formula to calculate the roots
x = ( - 2 ± 
) / 2
= (- 2 ± 4i ) / 2 = - 1 ± 2i
