JL and MK have the same value, because they link heights and lengths with the same proportion: Height KL = Height JM ; Length ML = Length JK. So you can conclude that you can do:

JL = MK
-> 2x + 5 = 7x - 40
-> 5x = 45
-> x = 45/5
-> x = 9

MK = ?
-> MK = 7x - 40
-> MK = 7.(9) - 40
-> MK = 63 - 40
-> MK = 23

JL=MK, therefore 2x+5=7x-40
5=5x-40
45=5x
9=x

7(9)-40= 63-40=23

LekaFEV [45]

Answer:

Done below!

Step-by-step explanation:

(x - root)

(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

(x^{2} +x-2x-2)(x+5)=(x^{2} -x-2)(x+5)=x^{3}+5x^{2}-x^{2}   -5x-2x-10\\\\=x^{3}+4x^{2} -7x-10
