The sides of an equilateral triangle measure 16 inches. the midpoints of the sides of the triangle are joined to form another equilateral triangle with sides that are half the length of the outer triangle. this process is continued until three triangles are inscribed in the first triangle. the sum of the perimeters of all four triangles is inches.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

step-by-step explanation:

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.
