Yes, by the time you add up all estimations, you must add taxes.
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>
It would have 3 solutions
if you solve the equation how it is, it give 1 solution but if you make the 1 negative you get 2 more possibilities
Answer:
no
Step-by-step explanation:
To find coterminal angles for a given angle
add/ subtract 360° from it
Thus
135° + 360° = 495° or 135° - 360° = - 225°
