Answer:
c Point E
Step-by-step explanation:
Remember coplanar means being on the same plane.
Look at each side/square as a plane. If we look closely, we can see that A, C, G, and E are on the same square/plane. E is coplanar.
-4x-2(8x=1)=-(2x-10)
-First, use the distributive property.
So distribute -2 to 8x=1 then distribute the negative - to (2x-10)
So it'd be: -4x-16x=-2=-2x+10
Then combine like terms:
-20x=-2=-2x+10
-18x=-2=10
-18x=8
Divide -18x by 8
x=-2.25
Well you can use the Pythagorean Theorem Formula a

+b

=c

. Just plug in the first 2 least numbers into a and b, and see if your answer(c) is equal to the last number. Hope I helped!
When you have a negative exponent, you move the base with the negative exponent to the other side of the fraction to make the exponent positive.
For example:
or 
or 
or 
Make the exponent positive
(this is as far as you can simplify)
We have 12 8-ounce bottles, so altogether we have 12 * 8 = 96 ounces of bottled water. If it all costs $3.36, than one ounce of bottled water costs $3.36 / 96 = $0,035.
