An equilateral triangle has an apothem of 5 cm. find the perimeter of the triangle to the nearest centimeter. a. 26 cm b. 52 cm c. 75 cm d. 100 cm

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.
