How do i write n squared is greater than 18
2 answers:
n^2>18
n^2 is n squared, > is the greater than symbol
Note
The open end of the < and > sign always opens up towards the largest amount. In this case n^2 is bigger than 18 so the expression you want is n^2>18.
This tells you that n^2 is larger than 18. Just to make it clearer suppose n = 5
Then what you get is 5^2 > 18? Is that true? 25 > 18 so yes it is true. 4^2 is not a solution because 4^2 = 16 which is smaller than 18.
One thing you should be aware of (-5)^2 > 18 is also true.

Answer:
Value of F(2) = 12
Step-by-step explanation:
Given:
F(x) = 7x - 2
Find:
Value of F(2)
Computation:
F(x) = 7x - 2
putting x = 2
f(2) = 7(2) -2
f(2) = 14 - 2
f(2) = 12
So, Value of F(2) = 12
