I believe it is 22 years.
Again, math questions do not go in the spanish field:)
Answer: 1. 95
2. 14
3. 102
4. 110
explanation:
1. In order to find the answer for number 1 we will have to count down from 99 because that is the greatest possible 2 digit number. We also know that a number that has a factor of 5 ends with a five, therefore 95 is the greatest two digit number with 5 as a factor.
2. now we have to start with 10 because that is the smallest 2 digit number and going up the 7 times table. 7 times 2 s 14 and that is the smallest two digit number.
3. since it says smallest 3 digit number we have to start at 100. 100 is not dividable with 3. 101 is not dividable by 3, but 102 is dividable by 3 making it the smallest three digit number.
4. again we have to start with 100. 11 times 10 is 110. 11 times 9 is 99 so we cant use 11 times 9. therefore 11 times 10 also know as 110 is the smallest three digit number.
Is this the mathematical one? If so the one i know is the one that says 12m and 9m
Perim=2l + 2l
2.12+2.9
24+18
42
