4n3 - 12n2 - 7n + 9
It means the radius squared.
100m^2-49n^2 (10m+7n)(10m-7n) the middle term cancels out.
A term.
7n(n−1)
7n = 91n = 91÷7n = 13
7n-6 = 1
I assume you mean what is the solution for the value of n. 4n+11-7n = -13 -3n = -24 n=8
n7-12
The term 7n means seven times some unspecified number. While this does not mean anything in isolation, it could be a meaningful part of an algebraic equation or other mathematical term.
-7n2 + 74n + 33 = -7n2 + 77n - 3n + 33 = -7n*(n - 11) - 3*(n - 11) = =(-7n - 3)*(n - 11) = -(7n +3)*(n - 11)

7n = 28n = 28/7 = 4
2 - 7n = 6therefore 7n = 2 - 6 = -4 and so n = -4/7 Then 5m + 7n = 6.4 becomes 5m - 4 = 6.4 so that 5m = 10.4 and then m = 10.4/5 = 2.08
9n-2=7n+50 7n+9n=50+2 16n=52 n= 3.25
