There should be 283.9. (rounded to the nearest unit). :) <span />
She drinks 4.27 grams on calcium in 14 days at one glass of milk containing 14 mg per day
<span>|x + y| + |z| = </span><span>|-6 + 4| + |-13| = </span><span>|-2| + 13 = 2 + 13 = 15</span>
6 is 5.5 because the length of GH is half of KL
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>
