Which sum or difference is modeled by the algebra
a. (x2 - 2x + 3) - (-x2 - 4x - 2) = 2x-1
b. (x2 - 2x - 3) + (x2 - 4x + 2) = 2x - 1
c. (x2 - 2x - 3) - (x2 + 4x + 2) = 2x-1
d. (x2 - 2x - 3) + (-12 + 4x + 2) = 2x-1

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

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 "
