The perimeter of a Pentagon is all the length of the sides added up
A pentagon is a five sided shape
so...
900+900+900+900+900
or 900*5
That is 4500.
The perimeter of the Pentagon Building in Washington DC, whose side is 900 feet long, is 4500 feet around.
Hope this helps :)
So 29-4 =25... which is a perfect square
Answer= +/- 5
6r - 3t = 6 /*8
6r + 8t = - 16 /*3
48r - 24t = 48
48r + 24t = - 48
---------------------- +
96r = 0
r = 0
t = ( -16 + 6r)/8 = - 16/8 = - 2

Answer:
x+18
Step-by-step explanation:
Let's simplify step-by-step.
2x+8−x+10
=2x+8+−x+10
Combine Like Terms:
=2x+8+−x+10
=(2x+−x)+(8+10)
=x + 18
