The answer is 69632 because of PEDMAS
2x + 3x = 100
5x=100
x=100/5
x= 20
Therefore, 2x=2×20=40
3x=3×20=60

Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is 
. With r=50, 
=2500π which is about (2500)(3.14)=7850.
The perimeter is 
which is the same as (diameter)(π). The diameter is 100, so 
which is about (100)(3.14)=314.
Subtract 15 from 7 and you get -8
So the answer is -8 degre C
