4 over 5n
It is 5n + 9r.
-4n3 + 8n2 - 4n + 7
In the equation 5n-11=4n+20, n is equal to 31.
(5n + 1)(n + 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
It is: 8n(5n+8)
5m-5n+5m+5n When simplified: 10m
9-5n+1 = 15 -5n = 15-9-1 -5n = 5 Divide both sides of the equation by -5 to find the value of n: n = -5
-2n - 4p + 2. Without knowing n and p, that's the best you get.
8n(5n+8)
mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
