<em><u>Explanation</u></em>
Xian has 52 stamps and Kai has 76 stamps.
Xian's club will send him 16 new stamps per month and Kai's club will send him 12 new stamps per month.
Suppose, Xian and Kai will have the same number of stamps after
months.
So, the total number of new stamps for Xian
and the total number of new stamps for Kai 
So, the equation will be......

Thus, Xian and Kai will have the same number of stamps after 6 months.
The number of stamps for each of them will be: 
The answer is C, because if you divide 4.20 by 3, you get 1.4, do you can multiply 1.4 by 5 and get 7.00
I believe it would be 25+25+15+15 = 80ft
120 feet
To find area you need to follow the formula l • w, which is 12 x 10, that equals 120
