Bis the midpoint of ac; ab = 9x+1, bc=2x+15

Question:

B is the midpoint of ac; ab = 9x + 1, bc = 2x + 15

To find ac you have to make into this form of equation:

9x + 1 = 2x + 15

Steps:

1. Subtract 1 from both sides:

2. Simplify,

3. Then, subtract 2x from both sides

4. Simplify,

5. Then, divide both sides by 7

6. Simplify,

So to find ac plug 2 in the x

9(2) + 1 + 2(2) + 15

7. Simplify,

Hope that helped!!!

AB = BC since B is the midpoint

9x + 1 = 2x + 15

7x = 14

x = 2

AC = 9(2) + 1 + 2(2) + 15 = 19 + 19 = 38 units.

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 "
