Answer:
It should have 20 vertices, and the name is dodecahedron
Use S=(n-2)180
S is the sum and N is the number of sides
If you know that the sum is 7560 then plug that in for S
7560=(n-2)180
Then solve for n
7560=180n-360 (note I used distributive property)
7560+360=180n
7920=180n
7920/180=n
n=44 sides
I hope this helps :)
Answer:
b = 5/2x + 7
Step-by-step explanation:
b + (-5/2x) = 7
b - 5/2x = 7
b = 5/2x + 7
The answer for this is A.
For this case we have that by definition, if we draw the diagonal of a square two rectangular triangles are formed. If the diagonal measures "x", then the Pythagorean theorem is fulfilled:

Where:
l: It's the side of the square.

We know that the area of a square is given by:

So, the area is:
