NEED TO KNOW THIS PLEASE Extra Pts 20 class=

Sagot :

By placing point K on the line segment JL, you now have two connected line segments JK and KL, and the total length of JL is equal to the sum of the lengths of JK and KL. So we have

4x + 9 = (5x + 2) + (2x - 2)

Solve for x :

4x + 9 = 7x

9 = 3x

x = 3

Then the total length of JL is

4x + 9 = 4•3 + 9 = 12 + 9 = 21
