Use mental math to solve for the missing number:

39

Step-by-step explanation:

Let the number be x.

The quotient of x and 3 is 13.

x/3 = 13

Multiply both sides by 3.

x = 13 × 3

x = 39

39

Step-by-step explanation:

The quotient of a number and 3 is 13. That's the same as saying n/3 = 13.

IF you multiply both sides of the equation by 3, you get n = 39, which is what we want.

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 "

c. (3,2,6) is the answer.
