N= 2/5! :)
n2 - 10n + 21 = 0 Two numbers that sum to -10 and multiply to 21 are -3 and -7 So (n - 3)*(n - 7) = 0
10n + 3 = 93 Therefore, 10n = 90 n = 90/10 n = 9
10n + 3 = 7n + 53n = 2n = 2/3
10n = 80.n = 8.
It has to be interval notation
If: 10n = 1,000,000 Then: n = 100,000
n=3
5n - 4 = 10n + 6-5n = 10n = -2
If: 10N = 25 Then: N = 2.5
10n = 90; divide both sides by 10 n = 9
10n = 1,000,000 n= 1,000,000 divide by 10 n= 100,000
10n+12 = 14n-12 10n-14 = -12-12 -4n = -24 n = 6
