Answer:
D) 900
Step-by-step explanation:
So I'm assuming the first part is jsut excess information
What we need to find is the sum fo the first 30 odd numbers -->
to simply calculate this, 1+3+5+7 ... +57+59, we can group the first and last numbers into pairs and so on. this gives us 60 as our first known number and 30/2= 15 pairs. -->
now we multiply 60x15 => 6x15 = 90 --> add 1 zero to the end and you get 900
Hope this helps!
