Kristin is building a pattern using triangles. The table shows the number of triangles in the first 4 terms of the pattern. Term Number (n) 1 2 3 4
Number of Triangles (t) 13 5 7
Which formula describes the number of triangles in the nth term of the pattern?

step-by-step explanation:

it's is b

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

the answer is y = 11.54

hope this : )
