An expression is shown below: 4(m + 3 + 5m) part a: write two expressions that are equivalent to the given expression. 2(2m+6+10m) 4m+12+20m part b: show that one of your expressions in part a is equivalent to the given expression using algebraic properties. explain which properties you used. part c: show that your other expression from part a is equivalent to the given expression by substituting a number for m.

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 "
