It is x4 + 11x3 + 41x2 + 61x + 30.
No, 1 + 2 + 3 + 4 + 5 = 15.
It is 77
It is: -9+8+(-5)+3+1 = -2
2/5 plus 1/3 plus 5/6 is equal to 1.57 or 1 57/100
2 + 1 + 3 + 5 + 14 = 25
3 + 5 + 6 + 9 + 2 + 1 + 10 = 36
1 + 2 + 3 + 4 + 5 + 6 + 100 = 121
30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
the answer to 2+3=5
2(1) + 3 = 5 2 + 3 = 5 x = 1
(n2 + n)/2 1+2+3+4+5+n= 15+n
