2 and 4
or is this question unfactorable and I have to use the quadratic formula??
Yes, each number is multiplied by 2 therefore the next 2 numbers in the sequence would be 80 & 160
2 x 7 x 7 = 98
The greatest common factor of the numbers 39 and 99 is 3.
-97
Well, darling, the sum of the first 99 odd numbers is 9801. You see, you take the last odd number, which is 197, multiply it by the total number of odd numbers (which is 99), and divide by 2. Voila! Math magic at its finest.
The prime factorization of 99 is: 3 * 3 * 11 = 99
396
99*99=9801
There are infinite numbers, but 11* 9 is fine.
-97
1 x 99 = 99 3 x 33 = 99 9 x 11 = 99
Prime factorization of 99 = 3 * 3 * 11
20%=.2 Multiply 99 by .2 99*.2= 19.8
3 times 33
99.Because if you do 0 minus 99 whats the answer?99.So it has 99 numbers in a 2-digit number.
