Sarah sees an antelope and a giraffe on a nature show. The antelope is 3 feet tall. The giraffe is 18 feet tall. How many times as tall as the antelope is the giraffe?

answer: the common difference is -0.10

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 solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

ya

the answer to this is a. a^2 + b^2 = c^2
