Answer:
A
Step-by-step explanation:
I just plugged each variable into the equation. A is the only one that works.
The first two days he will both swim and bike are days 24 and 56.
Swim: Days 6,12,18,24,30,36,42,50,56
Bicycle: Days 8,16,24,32,40,48,56,
AD = 14
BC = 6
BD = 8
CD = BD - BC
CD = 8 - 6
CD = 2
Since B is the midpoint of AC, therefore:
AC = 2*BC
AC = 2*6
AC = 12
Thus:
AD = AC + CD
AD = 12 + 2
9^2= (x+2)^2+(y+8)^2
The equation is r^2=(x+h)^2+(y-k)^2
Answer: To just make my answer simple, your answer will be : 28/3, the exact form.
Hope this really helps you, have a nice daayy!! :)
