Answer:
Step-by-step explanation:
If x=9, then x^2=81, because 9*9=81. -x^2=81, because -9*-9=81, and (-x)^2=81, because -9*-9=81.
If x=6, then x^2=36, because 6*6=36. -x^2=36, because -6*-6=36, and (-x)^2=36, because -6*-6=36.
Answer:
The sum of all integers is 774.
Step-by-step explanation:
Since √11 = 3.3166, and 3.3166 is not an integer, so the first integer is 4.
From 1 to 39, there are 39 integers. But we started with 4, so we take out 3 numbers (1, 2, 3). Therefore, there are 39 - 3 = 36 numbers left.
The total number between 4 and 39 is 36 = n.
Sn = n/2 x (a1 + an)
S36 = 36/2 x (4 + 39) = 18 x 43 = 774
