If a b c=0, but abc don't equal 0, then a^2/bc b^2/ca c^2/ab=

goblinko [34]

$\sf a + b + c = 0\\abc \neq 0\\\\ \frac{a^2}{bc} + \frac{b^2}{ac} + \frac{c^2}{ab} = \frac{a^3+b^3+c^3}{abc} \\\\\sf Formula: \\a^3 + b^3 + c^3 = (a + b + c) (a^2 + b^2 + c^2- ab - bc - ca) + 3abc\\\\\frac{a^3+b^3+c^3}{abc}= \frac{(a + b + c) (a^2 + b^2 + c^2- ab - bc - ca) + 3abc}{abc}\\\\\sf However, ~a+b+c = 0. ~So:\\\\\frac{0 (a^2 + b^2 + c^2- ab - bc - ca) + 3abc}{abc}\\\\\sf Multiply~ anything ~by~ 0, ~and~ you ~get~ 0. ~So~ simplifying:\\\\\frac{3abc}{abc} = \boxed{3}$

Your final answer is 3.

Veronica is buying cubed cheese from Mr.Sands deli.she asks for 1 3/4 pounds. When Mr.Sand places some cheese in a container and

nirvana33 [79]

Amount of cubed cheeses that Veronica wants to buy =1 3/4 pounds

=7/8 pounds
Weight of the container in which Mr. Sand places the cube =1/16 pounds
Weight of the cubed cheese and container together =1 1/4 pounds
=5/4 pounds
Then the amount of cubed cheese placed by Mr.Sands =(5/4-1/16) pounds
=(20-1)/16 pounds
=19/16 pounds
So the quanity of more cheese that Mr.Sands need to add to the scale =(7/4-19/16)pounds
=(28-19)/16pounds
From the above debuction we can easily conclude that Mr.Sand need to add 9/16pounds of cubed cheese to fullfil the order placed by Veronica
