Answer: The difference between sum of first 20032003 even numbers and sum of first 20032003 odd numbers is “-20032003”.
Step-by-step explanation:
The sum of first 20032003 even numbers:
The sum of first 20032003 odd numbers:
Difference between the sum of first 20032003 even numbers and the sum of first 20032003 odd numbers:
Even numbers start as 0, 2, 4, 6…. While odd numbers start as 1, 3, 5, 7…..
(assuming that we are taking non-negative even/odd numbers into account only)
As we know, every nth even number is one behind their respective odd number (i.e. 0 lags 1, 2 lags 3, 4 lags 5 and so on)
Thus, our equation of difference becomes,

Answer:
I believe the answer is X=2.5
Step-by-step explanation:
7+2=9
so now we have to find what X would be so we can do the second equation
So we know that the second equation must equal 6 because 9+6=15
So now we experiment with different numbers for X
if we did 2, the new equation would be 2x2+1 which is 5, too low
if we did 3, the new equation would be 2x3+1 which is 7, too high
So we need something in the middle
in the middle of 5 and 7 is 6 which is the number we need
so to get 6 we need something in between 2 and 3, which in 2.5
hope this helped!

Answer:x^4-2x^3-17x^2+8x+72
Step-by-step explanation:
X=3 x=-3 x=4 x=-2
(X-3)(x+3)(x-4)(x+2)
(X^2-9)(x^2-2x-8)
X^4-2x^3-8x^2-9x^2+8x+72
X^4-2x^3-17x^2+8x+72
Answer:
Out of town teenagers = 30
Step-by-step explanation:
Given that,
Total number of teenagers at a swim meet = 50
Let there are 2x locals and 3x out of town participants. The ratio of locals to out-of-town participants is 2:3.
ATQ,
2x+3x = 50
5x = 50
x = 10
Out of town teenagers = 3x
= 3(10)
= 30
Hence, there are 30 teenagers travelled from out-of-town to the swim meet.
