Answer:
Step-by-step explanation:
An negative exponent seems hard, but it really isn't!
Let's say you have
All you do is inverse the expression, or find the reciprocal. When you do this the exponent changes to positive .
simplifies into 8. So, the result is

<h2>7. 12</h2><h2>8. -√18</h2><h2>9. √220</h2>Step-by-step explanation:
To find out which is greater, we must eliminate the radical symbol.
#7
= 9.38083151965
9.4 < 12
#8
= -4.24264068712
-4.2 > -6
#9
= 14.8323969742
14.5 < 14.8
I'm always happy to help :)
Answer:
Step-by-step explanation:
The base of the pyramid we need to study is a hexagon.
Let's look at the attached image of an hexagon to understand how we are going to find the area of this figure.
Notice that an hexagon is the combination of 6 exactly equal equilateral triangles in our case of size "2x" (notice that the "radius" of the hexagon is given as "2x")
Therefore the area of the hexagon is going to be 6 times the area of one of those equilateral triangles.
We know the area of a triangle is the product of its base times its height, divided by 2:
We notice that the triangle's height is exactly what is called the "apothem" of the hexagon (depicted in green in our figure) which measures , so replacing this value in the formula above for the area of one of the triangles:
Then we multiply this area times 6 to get the total area of the hexagon (6 of these triangles):
Area of hexagon =
which is the last option given in the list.
