12.5 minutes becuase 25ft divided by 2 ft is 12.5

The first point is (x1,y1). The second point is (x2,y2)
Since the first point is (-1, -3), we can say (x1, y1) = (-1, -3)
So ,
Since the second point is (-4, -8), we can also say (x2, y2) = (-4, -8)
So ,
Put this all together to get: , , , and </span>
The distance between the center and any point on the circle is the radius. That's likely what your book or teacher is asking for.
Note: double the radius and you get the diameter
Hey!
---------------------------------------------------
Solution ↓
The question is asking you turn this mathematical explanation to standard form.
Eight more: + 8
Three times a number: (3 * n)
Equals: =
Four less than a number: n - 4
---------------------------------------------------
Final Answer ↓
(3 * n) + 8 = n - 4
---------------------------------------------------
Hope this helped! Good Luck!
AC+CE=AE
Pythagorean theorem is a big part of this problem. a^2+b^2=c^2
Part AC
8^2+6^2=c^2
64+36= 100
c^2 =
or
5^2 to match c^2.
Part CE
It is similar to the other one. It's just scaled. 6 to 8, 4 to....6
4^2+6^2=c^2
16+36=52
c^2 =
It is not a perfect square. So that will be the answer.
