n = +5 or -5
25
4n2-25 = 0 4n2=25 n2=6.25 n=sqrt(6.25) n= +2.5 or -2.5
"x squared equals to 25" is not an inequality! You need to re-think the question!
If: n2 = 19 Then: n = the square root of 19.
N2
Conditional statement: If n2 equals 64, then n equals 8, where n2 equals 64 is the hypothesis, and n equals 8 is the conclusion. In order to obtain the converse of the conditional we reverse the 2 clauses, then the original conclusion becomes the new hypothesis and the original hypothesis becomes the new conclusion. So that, Converse: If n equals 8, then n2 equals 64.
no. 33 is an answer though.

4x+9=25 4x=16 x=4
5r = 25 is a linear equation in one variable, r. The solution is r = 5.
The solution is made up of 20% O2 and 80% N2 based on the volumes provided.
n2 + 9n + 18 = (n + 6)(n + 3)
