16+3/7-(12+2/5)=16-12+3/7-2/5=4+(3*5-2*7)/35=4+1/35
3m+5=8
subtract 5 from both sides
3m=3
divide both sides by 3
m=1
I hope I helped! :)

Answer:
D
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
Here r = 15, thus
x² + y² = 15² , that is
x² + y² = 225 → D
