Answer:
I think you have to multiple them all around the triangle
Answer:
60(a+b) means that you would have to distribute
While 60a+ 60b is already in it's simplest form
I can do my best to help, but I am only taking geometry right now so I might not know all the answers
The length of BC is equivalent to 12 units
<h3>Midpoint of a line</h3>
If the midpoint if Ac is B, then the expressions below are true;
AB+BC = AC
AB = BC
Given the following parameters
AB = x + 6, and
AC = 5x - 6
BC = x + 6
Substitute
x+6+x+6 = 5x - 6
2x+12 = 5x - 6
2x-5x = -6-12
-3x = -18
x = 6
Determine the measure of BC
BC = x + 6
BC= 6 + 6
BC = 12units
Hence the length of BC is equivalent to 12 units

The circumference of a circle is 2PiR
We have 32Pi, so we can divide 32 by 2 to get the radius
The radius is 16.
The diameter is 2x the radius.
The diameter is 32.
Your answer is B.)
