Answer:

k=[tex]\sqrt{129}[/tex]-10=1.357816691600547or k=[tex]-\sqrt{129}[/tex]-10=-21.35781669160055

Step-by-step explanation:

k^2-20k=29 |+100

k^2-20k+100=29=100

k^2-2x10xk+(-10)^2=129

(k-10)^2=129

|k-10|=[tex]\sqrt{129}[/tex]

case 1 k is a positive number

case 2 k is a negative number

hope this helps
