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"
Probably that it was # 766 of an 18k Design.
18k refers to the gold content (18k = 75% gold) with the rest being silver or other metals 159 refers to the purity of the silver
k
66.5
Just a pair of straight vertical lines, one on either side of the number. The absolute value of 18k is |18k| . The absolute value of 'x' is |x| .
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
2 x 3 x 3 x k = 18k
LHGE is the logo of the company who made the piece.
yes
Its 18k plus 2k for your kit
18k means it is 18 carat gold. IDGC is the maker's mark but I am not sure who that maker is unless you look it up in reference.
6 separate 18kOhm resistors wired in series make a total resistance of:18k+18k+18k+18k+18k+18k which is 108 kOhm.6 separate 18kOhm resistors wired in parallel make a total resistance of:1/[(1/18k) + (1/18k) + (1/18k) + (1/18k) + (1/18k) + (1/18k)] which is 3 kOhm.
what does 18K SAC mean in a ring
Probably that it was # 766 of an 18k Design.
What's is 18k TCH nice
18K HGE = 18K Heavy Gold Electroplate = plated and not solid 18K gold ESPO = maker ESP) is Esposito Jewelry whilst ESPO/SIG = joseph esposito
18k means 18 prosperous years has passed..
