F:m:s=4:5:7
s=f+18 and from above we see s/f=7/4 so s=7f/4 now we can say:
f+18=7f/4
4f+72=7f
3f=72
f=24 and we know s=f+18 so
s=42
m/s=5/7 so m=42*5/7=30
So Frank got 24, Mary got 30, and Seth got 42.
Answer:
The required equation in standard form is 
Step-by-step explanation:
The equation of a circle with center (h,k) an radius, r units is given by the formula;

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is 


We substitute these values into the formula to obtain;

We simplify to get;
