The area of square flake of gold is 
<h3><u>Solution:</u></h3>
Given that width of square flake of gold is 
millimeter
To find : Area of square flake
Since gold flake is in shape of square, we can use area of square formula
<em><u>The formula for area of square is given as:</u></em>
where "s" is the length of one side
Hence , the calculated area of flake is
A. ) Addition Property is the answer
The three points give you three equations, which you can solve by your favorite method.
.. 0m +0n +b = 6
.. 1m +0n +b = -3
.. 0m +2n +b = 5
(m, n, b) = (-9, -1/2, 6)
so the equation of the plane can be written as
.. z = -9x -1/2y +6
_____
In standard form, this would be
.. 18x +y +2z = 12
Answer:
I would assume you're referring to this test? if so the answer is
a, d and e
Answer:
x and y do not show direct variation.
Step-by-step explanation:
The formula for direct variation is
y = kx Divide each side by y
k = y/x
k should have the same value for every point except, of course, (0,0)
For the first point,
k = 2/(-1) = -2
For the third point,
k = 2/1 = 2
The values of k are different, so x and y <em>do not</em> show direct variation.
