You have to add all the #s then divide by the amount of #s in this case you would divide by 7 because there are 7 #s shown. The answer would be 8 because you add all the #s getting 56 then divide by 7 to get 8 as your final answer.

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.
