k + 18k + 81 = 19k + 81 which cannot be factorised.
HOWEVER
If the question was about k2 + 18k + 81, but was foiled by the inability of this browser, then the answer is
k2 + 18k + 81 = (k + 9)2
30=18k

Yes, "18k" typically means 18 thousand. The "k" is an abbreviation derived from the Greek word "kilo," which signifies a factor of one thousand. This notation is commonly used in various contexts, such as finance and social media, to denote large numbers succinctly.

To factor this, find two numbers whose product is 81 and sum 18. These two numbers are therefore 9 and 9. So we can rewrite the polynomial in its factored form as follows: (k+9)(k+9), or "k plus 9 squared"
2 x 3 x 3 x k = 18k
30=18k
k
The factors of 27 are: 1, 3, 9, 27 The factors of 45 are: 1, 3, 5, 9, 15, 45 The factors of 81 are: 1, 3, 9, 27, 81
Using the discriminant the possible values of k are -9 or 9
18 K
mabye 18k is 18000
6*3= 18k+18= 48-18 -18k= 30
18k kg stands for 18,000 kilograms. The "k" represents the prefix "kilo-," which means thousand.
GB gold bonded not solid.... So it would be 18 k gold bonded to a metal.
k = -3; factors are (9x + 3)(x - 1)
