Answer:
x=66.667
Step-by-step explanation:
Basically, if y varies directly with a value x, you get an equation of the form y=kx, where k is a constant. To answer the question, first substitute 9 into y, and 24 into x.
9=24k
k=0.375
k is 0.375, so to get x, substitute 0.375 into k and 25 into y
25=0.375x
x=66.667
And we got it!

Answer:
The area of the regular pentagon is 
Step-by-step explanation:
we know that
The area of a regular polygon is equal to
where
P is the perimeter of the regular polygon
a is the apothem
Find the perimeter P
----> the regular pentagon has five equal sides
---> distance from center to middle of side
substitute
