Which of the following is the complete factorization of 25a 2-100

25(a-2)(a+2)

Step-by-step explanation:

25a^2 -100  

We can factor out 25

25(a^2 -4)

a^2 -4  is the difference of squares a^2-b^2= (a-b)(a+b)

where a =a and b=2

a^2 -4 = (a-2)(a+2)

25a^2 -100 = 25(a-2)(a+2)

answer

point o.

step-by-step explanation:

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 "
