Laura needs your help. She needs to order expensive wire to connect her sound system to her built-in speakers and would like your help to save her money. She plans to place her sound system somewhere on a cabinet that is 8 feet wide. Speaker A is located 6 feet above one end of the cabinet, while speaker B is located 4 feet above the other end. She will need wire to connect the sound system to speaker A, and additional wire to connect it to speaker B. Where should she place her sound system so that she needs the least amount of wire?
