The expression 35 - 5n can't be evaluated until you assume a value for n. However, it can be made simpler, in a way, by separating the common factor, 5: 35 - 5n = 5(7-n).
35-5n = 30
Substitute the values 1, 2, 3, etc for n in 35 - 5n
5n-25 = 10 5n = 10+25 5n = 35 n = 7
5n if n = 7 is 5 x 7, or 35.
The GCF is 5n.
t(n) = n2 + 5n - 1
what does the expresstion 5n represent
5m-5n+5m+5n When simplified: 10m
5n=30n=30/5n=6
-5n - (-2) = 27 -5n + 2 = 27 -5n + 2 - 2 = 27 - 2 -5n = 25 -5n/-5 = 25/-5 n = -5
4 over 5n
5n
