Since, a regular hexagon has an area of 750.8 square cm and The side length is 17 cm.
We have to find the apothem of the regular hexagon.
The formula for determining the apothem of regular hexagon is
, where 's' is any side length of regular hexagon and 'n' is the number of sides of regular hexagon.
So, apothem = 
= 
= 
= 14.78 units
Therefore, the measure of apothem of the regular hexagon is 14.7 units.
Option B is the correct answer.
Multiply $530.40 by 3/4. You get the equation

If you simplify this, you get the solution of $397.80
$397.80
X+5=18
first get rid of the 5
so X+5-5=18-5
which makes X=13
if any questions please ask
Using the side of the square find the area:
Area = 30^2 = 900 square feet.
The rectangles area is the same, 900 square feet.
Let the width = X
The length would be 2X + 70
Area = length x width
X * 2x+ 70 = 900
This expands to 2x^2 * 70x = 900
Use the quadratic formula to solve for x:
-70 +/- sqrt(70^2-4*2(-900))/2*2
X = 10
Width = x = 10 feet
Length = 2x + 70 = 90 feet
The answer is x= 3.3 and the y=-., hope this helps out !
