Answer:
-2/5
Step-by-step explanation:
(6 - 8) / (3 - (-2)) = -2 / (5) = -2/5
According to the properties of parallelograms the diagonals bisect each other. What this means is that each "half" of a diagonal is equal to each other. With this in mind you can set each half equal to each other in an equation like so...
3x + 3 = 6x - 57
Now you must combine like terms
60 = 3x
Isolate x by dividing 3 to both sides
60/3 = 3x/3
20 = x

<u>Step-by-step explanation:</u>
a₁, 375, a₃, a₄, 81 , a₆
First, let's find the ratio (r). There are three multiple from 375 to 81.
![375r^3=81\\\\r^3=\dfrac{81}{375}\\\\\\r^3=\dfrac{27}{125}\qquad \leftarrow simplied\\\\\\\sqrt[3]{r^3} =\sqrt[3]{\dfrac{27}{125}}\\ \\\\r=\dfrac{3}{5}](https://tex.z-dn.net/?f=375r%5E3%3D81%5C%5C%5C%5Cr%5E3%3D%5Cdfrac%7B81%7D%7B375%7D%5C%5C%5C%5C%5C%5Cr%5E3%3D%5Cdfrac%7B27%7D%7B125%7D%5Cqquad%20%5Cleftarrow%20simplied%5C%5C%5C%5C%5C%5C%5Csqrt%5B3%5D%7Br%5E3%7D%20%3D%5Csqrt%5B3%5D%7B%5Cdfrac%7B27%7D%7B125%7D%7D%5C%5C%20%5C%5C%5C%5Cr%3D%5Cdfrac%7B3%7D%7B5%7D)
Next, let's find a₆ which is one multiple from 81.
