Answer: 4, -1, [see if you can figure it out]
Step-by-step explanation:
Answer:
111 minutes
Step-by-step explanation:
step 1
Find out how long are the six commercial
Multiply the number of commercials by 90 seconds
so
Convert to minutes
Remember that
step 2
Subtract the duration of six commercials from the duration of the program
Remember that
so
therefore
But what is the expression, you have to tell me so I can do it.
<h3>
Answer: C) incenter</h3>
========================================
Explanation:
If you were to intersect the angle bisectors (at least two of them), then you would locate the incenter. The incenter is the center of the incircle which is a circle where it is as large as possible, but does not spill over and outside the triangle. Therefore this circle fits snugly inside the triangle.
--------------
extra notes:
* The centroid is found by intersecting at least two median lines
* The circumcenter is found by intersecting at least two perpendicular bisector lines
* The orthocenter is found by intersecting at least two altitude lines
* The incenter is always inside the triangle; hence the "in" as part of the name. The centroid shares this property as well because the medians are completely contained within any triangle. The other two centers aren't always guaranteed to be inside the triangle.
* The red lines cut each angle of the triangle into two equal or congruent pieces.
The perimeter is just the sum of all of the side lengths.
p=3x+4+x-10+5x-2
p=9x-8
