Which expression describes the total number of triangles in figure n?
The expression that describes the total number of triangles in figure n is n(n+1)(n+2)/6. This can be derived using the formula for calculating the sum of the first n natural numbers, which is n(n+1)/2, and then multiplying it by (n+2)/3 to account for the different possible combinations of vertices in a triangle.
What best describes the English expression two more than the quantity of a number minus seven?

Can a isoceles triangle be a polygon?
A polygon is a plane figure bounded by a finite number of straight lines. To enclose an area then a minimum of three straight lines are required. All triangles, not just isosceles triangles, are polygons.

Can a isoceles triangle be a polygon?
A polygon is a plane figure bounded by a finite number of straight lines. To enclose an area then a minimum of three straight lines are required. All triangles, not just isosceles triangles, are polygons.
How many triangles are in a 26 sided polygon?
To determine the number of triangles in a polygon, we can use the formula n(n-1)(n-2)/6, where n is the number of sides of the polygon. For a 26-sided polygon, the formula would be 26(26-1)(26-2)/6. Simplifying this expression, we get 262524/6 = 10400 triangles.
