Step-by-step explanation:
Data:
Amount of money per hour: X $
Amount of hours worked: 8h.
Amount Earned: Y $
<u><em>In case, you know X (AMOUNT OF MONEY PER HOUR): </em></u>
One hour (1h) is equivalent to X.
Eight hours (8h) - How much would it be?
Answer:
1. Multiply 8 (numbers of hour worked) per X (amount of money per hour)
Example 1:
If X = 10$
8 hours * 10 $ = 80$
Juan worked 8 hours, and earned 80$
Example 2:
If X = 20$
8 hours * 20$ = 160$
Juan worked 8 hours, and earned 160$.
<u>In case you know Y</u><u><em> (TOTAL AMOUNT EARNED)</em></u>
Eight hours (8h) are equivalent to Y.
One hour - How much would it be?
Answer:
1. Divide Y into total hours worked (8H).
Example 3:
If Y = 200$
200 $ / 8 hours = 25$
Per hour Juan earns 25$
Example 4:
If Y = 400$
400$ / 8 hours = 50$
Per hour Juan earns 50$.

Step-by-step explanation:
You want to put this in the form (x+b)^2 + c
To do this take half of the coefficient of b from the ordinal form which is 6/2=3 as use this as your new b
This give you (x+3)^2.
If you foil this out you get x^2 +6x +9 so you have added 9 to the original expression so now all you need to do is subtract 9 to keep things balanced
The final expression then is (x+3)^2 -9
<u> So c= -9</u>
