Answer:
Step-by-step explanation:
the expression we have is:
To find an equivalent expression, it would be helpful to express 1/3 so that it has a 12 in the denominator:
so we substitute this:
and now we have 1/12 in both terms :
so we can factor it (we take it out of each term: in the first we are left with -x and in the second with -4):
the equivalent expression is:
Answer: P = 166 units
Step-by-step explanation: Each point on the triangle has lines that are tangent to the circle in the triangle, meaning that those lines form a 90° angle to the middle point in the circle. There is also a rule that states if there are tangent lines coming from the points and if the points have at least one given side length, the other side will have the same side length. So if one side on point D is 41, then the other side connected to the point is 41. I added up all of the side lengths; 41 + 41 + 30 + 30 + 12 +12 = 166 units.
I hope this helps!
