The sum of the first n odd numbers is n squared! So, the short answer is that the sum of the first 70 odd numbers is 70 squared, i.e. 4900.
Allow me to prove the result: odd numbers come in the form 2n-1, because 2n is always even, and the number immediately before an even number is always odd.
So, if we sum the first N odd numbers, we have

The first sum is the sum of all integers from 1 to N, which is N(N+1)/2. We want twice this sum, so we have

The second sum is simply the sum of N ones:

So, the final result is

which ends the proof.

Answer:
z = 110
Step-by-step explanation:
z + 35 + 35 = 180
z+70=180
z = 110
Answer:
True
Step-by-step explanation:
That is the definition of a asymptote. It is approached but will never get to the line.
Answer:
yes if u use Pemdas and both sides of the equation have the same answer, they both are equivalent.
Good job!
