N plus 28 is a math equation. N would stand for an unknown number. You would add 28 to this unknown to find the answer.
-53+n = -28 n = -28+53 n = 25
28 + N = 68 Subtract 28 from each side: N = 40
n = 28
23+n+5+n=23+5+n+n=28+2nIt depends what n is, once, you find out what n is equal to, plug it in to the equation above in bold.
It means that a + n + mc + cg = 0
n = 7. 3(7) + 7 = 28. 21+7=28
Assuming you mean n2 + 11n + 30, the factors are (n + 6)(n + 5).
n plus 15.n plus 15.n plus 15.n plus 15.
I assume that with n(...) you mean the size of the set. It sure can; but it need not be.
28
They have n in common.
Oh, dude, let me break it down for you. So, you plug in n as 6 and m as 4, and you get 12 over 6 plus 7 times 4. That simplifies to 2 plus 28, which equals 30. So, the answer is 30. Easy peasy, lemon squeezy!
