A fraternity name formed by two letters would have 24 choices for the first letter, and 24 choices for the second, therefore 24*24=576 is the correct answer.
Let's list what we know.
We know 6 + d is the same as 21
We can use this.
6+d=21
Subtract 6 from both sides
d=15
So d=15
The graph in the top right—-when trying to figure these out, just plug numbers in for x to find the y.
For example: plug 0 in for x on both equations—
2^0 -1=0 so you get it passing thru 0,0
0+2=2 so it passes through 0,2
Answer:
6,12,18,24,30,36,42,48,54,60... All of the numbers in this list can be divided by 6 with no remainder.
A natural number that has at least one factor other than 1 and itself.
