Evaluate the following expression using the values given:

find x3 − 2y2 − 3x3 + z4 if x = 3, y = 5, and z = −3.

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.

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