Step-by-step explanation:
It is supposed that K lies on the line JL. Also, JK = 4n+3 and KL = 2n+7.
JL = JK + KL
Put the values of JK and KL, we get :
25 = 4n+3+2n+7
Taking like terms together,
25-3-7=4n+2n
15 = 6 n
n = [tex]\dfrac{15}{6}=2.5[/tex]
Put n in JK = 4n+3 = 4(2.5) +3 = 13
Put n in KL = 2n+7 = 2(2.5) +7 = 12
