Jamal is using the distance formula to find the length, d, of the line segment. His work so far is shown. What is Jamal's next step? Jamal should find the a(midpoint of each leg) b(midpoint of d) c(length of each leg)
by a(adding the x coordinate and y coordinate) b(squaring x coordinate and y coordinate) c(subtracting x coordinate and y coordinate)
