Answer:
C
Step-by-step explanation:
Remark
You must do the changes in order. Add 1 then multiply by 2
- First entry: 6
- Add 1: 6 + 1 = 7
- Multiply by 2 = 2*7 = 14
- Add 1: 14 + 1 = 15
- Multiply by 2: 15 * 2 = 30
Answer: 7 14 15 30
Answer:60
Step-by-step explanation:
Step-by-step explanation:
the distance of a vertex on the 2 outgoing sides to the touching points with the inscribed circle is the same for both sides.
and that applies to all 3 vertexes.
so, we know for the top left vertex the distance to both touching points is 4.
that means the distance to the touching points from the bottom left vertex is 7-4 = 3.
and that means that the distance to the touching points from the bottom right vertex is 16-3 = 13.
so, x = 13
it is the distance to one of the touching points for the bottom right vertex.
and the perimeter of the triangle is therefore
7 + 16 + (13 + 4) = 40
So I'm not totally sure but I got -15.32
So sorry if it's wrong!!
