Ab+ac=a(b+c) where a is the greatest common factor
find greatest common factor of 10 and 50
10=1,2,5,10
50=1,2,5,10,25,50
greatest common is 10
a=10
10(1)+10(5)=10(1+5)=10(6)=60

Answer:
3.1% increase
Step-by-step explanation:
Diameter1=25cm
Radius1=12.5cm
Circumference1=2x22/7x12.5
Diameter2=25.8cm
Radius2=12.9cm
Circumference2=2x22/7x12.9
% increase =Circumference2-Circumference1/Circumference2 x 100%= 2x22/7x12.9-2x22/7x12.5 / 2x22/7x12.9 x100%
12.9-12.5/12.9 x 100%
0.4/12.9 x 100%
4/129 x 100%
3.1%
