Answer:60mm
Step-by-step explanation:
15+20+25 =60
C. (2.4) because that point is the only one that is in both the blue and red shaded areas.
Area 512
area a = s^2
a = (8^(3/2))^2 = 8^((3/2)*2) = 8^3 = 512
Let m the tens digit and n the ones
the Original number is 10m+n
7(m+n) =10m+n
7m+7n=10m+n
6n=3m
Reversing the number 10n+m
10n+m=18+n+m
9n=18
n=2
6n=3m
6(2)=3m
3m=12
m=4
the number is 10m+n=10(4)+2=42
