They are +/- 5*sqrt(2)
79 + k = 84 84 - 79 = k k = 5
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
k2 + 3k =108k2 + 3k - 108 = 0(k - 9) (k + 12)k = -9 , k = 12ANSWER:k = -9 , k = 12I hope this helps!
k = 0.1
k equals 5.6
They are +/- 5*sqrt(2)
79 + k = 84 84 - 79 = k k = 5
If: 25k+12 = -13 Then: 25k = -13-12 => 25k = -25 So: k = -25/25 => -1
11k+9=42 11k=33 k=11
Using the discriminant the possible values of k are -9 or 9

Wow 757 wow 757 so 45 cook 1559
Yes, they are exactly the same, both of them increment k in 1.
k = 0.1
(k+3)/8 = 5/9 Cross Multiply: 9(k+3) = 5*8 Distribute: 9k+27 = 40 Subtract 27 from each side: 9k = 13 Divide each side by 9: k = 13/9
