This is completing the square:
(x^2+12x+36)+42-36
Answer: (x+6)^2 +6
I can give you a link https://youtu.be/aUy-_WnEV30 . I hope this answers your problem, and gives you greater insight. Sorry I couldn't do more :(
Bring the 3 to the other side, which makes 11-3 = 8
divide the whole equation by 2, which makes it Root (3x/5) = 8/2
square the whole equation which gives
, 3x/5 = 16
Multiply the equation by 5 which makes it, 3x = 80
finally divide the equation to find x, x= 80/3
Answer:
15/100 which equals 3/20
Step-by-step explanation:
Put 100 below to any decimal that has 2 numbers after zero then simplify
As the given values are
<span>ΔHf° = –423 kJ/mol
</span>ΔHsub = 119 kJ/mol
IE = 469 kJ/mol
ΔHEA = –301 kJ/mol
BE = 161 kJ/mol
The lattice energy of the compound can be determined by applying formula
U = <span>ΔHf° - </span>ΔHsub - BE - IE - ΔHEA
by putting values
U = -423 - 119 - 161 - 469 - (-301)
solving further
U = -871 kJ/mol
so the lattice energy is 871 kJ/mol
hope it helps
