A39-foot-long speaker wire is to be cut into three pieces. one piece is to be 13 feet long. of the remaining pieces, one must be 2 feet less than 3 times the length of the other. find the length of the shorter piece

the answer is d

hope this

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
