n=6
What is 3n squared minus 5n minus 4n cubed plus 5n squared plus n plus 7?
Assuming you meant 7n (not just 7 at the end of your question) - first... simplify the equation. Numbers raised to powers get priority - so your new sum is... 5n - 64n + 25n + n + 7n.... This simplifies to... -26n
What is 3n-9 plus 4n equals 8n?
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
What is 7n-2 plus 3n plus 4 equals?
10n+2

What is 7nĀ²-3n equals 0?
n(7n-3) = 0 n = 0 or n = 3/7
What is 3n-9 plus 4n equals 8n?
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
What is 7n-2 plus 3n plus 4 equals?
10n+2
7n plus 2y-3n plus y equals?
4n + 3y
What is the perimeter of 7n plus 2 plus 6 plus 5n plus 7n plus 3n equals?
22n + 2.
