(2/3)k
15-k
An algebraic closure is of a field K is an algebraic extension of K which is algebraically closed - that is, it contains a root for every non-constant polynomial in F(x).
If you mean: kk-5 then it can be k^2-5 But if you mean: k+k-5 then it can be 2k-5
knots
k - 6
As an algebraic expression it is: k-3
k > 10
The algebraic expression is 6x+k
Algebraic expression 14 less than the quantity k times 6
k-2.5 An algebraic expression is just using variables (in this case, k) for unknown numbers. Since the question is asking what the number k minus 2.5 is, your answer is k-2.5.
It is: 7k
