5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
(5n + 1)(n + 7)
A - B = -3n + 2 - (5n - 7) = -3n + 2 - 5n + 7 = 9 - 8n
-4n3 + 8n2 - 4n + 7
7
That depends what the value of n is.
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
5n + 7 = -41 5n = -48 n = -48/5 n = -9.6
If 5n + 8 = 43, then n = 7
the answer is 12.12.
(5n + 1)(n + 7)
A - B = -3n + 2 - (5n - 7) = -3n + 2 - 5n + 7 = 9 - 8n
first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
4n
5n + 7 = 28 + 2n (-2n) 3n + 7 = 28 (-7) 3n = 21 therefore, n = 7
