The cost to produce a product is modeled by the function f(x) = 5x2 − 70x + 258, where x is the number of products produced. Complete the square to determine the minimum cost of producing this product. A: 5(x − 7)2 + 13; The minimum cost to produce the product is $13.
B: 5(x − 7)2 + 13; The minimum cost to produce the product is $7.
C: 5(x − 7)2 + 258; The minimum cost to produce the product is $7.
D: 5(x − 7)2 + 258; The minimum cost to produce the product is $258.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153
