Question

Find the length of MN.​

Answer 1

Explanation:

MP = MN + NP

39 = 4(x+5) + 2x+1

39 = 4x + 20 + 2x + 1

39 = 6x + 21

6x = 39-21

6x = 18

x = 3

Then,

MN = 4(3+5)

= 4×8

= 32

Answer 2

32

Explanation:

39 = 4(x + 5) + 2x + 1

39 = 4x + 20 + 2x + 1

39 = 6x + 21

18 = 6x

x = 3

MN = 4(x + 5)

MN = 4(3 + 5)

MN = 4(8)

MN = 32

hope this helped!
