The answer is 2.5
2(10) = 20
20 + 5 = 25
25/10 = 2.5/1 = 2.5

in case you have an expression in terms of x, as yours is, and an x value (x = 10), all you ought to do is replace each and every x interior the expression with the x value. So the place f(x) = 4x + (10/x) f(10) = 4 situations 10 + (10/10) =40 + a million =40-one as a result, the answer to the expression is f(10) = 40-one
