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
Na+-K+ ATPase
K+15
0
When a number is given followed by K it means the weight of the gold. Most have 10K, 12K, 14k and 18k. I have never seen 40k.
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
k
30=18k
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)
