The sum of 7-1 and 7-2 will be a rational number because sum of rational numbers is a rational numbers.
A rational number is a number which can be written in p/q form where q≠0.
We know that when two rational numbers is added then the sum is also a rational number. And when two rational numbers are subtracted then the difference is also a rational number.
So in the given question, lets study the term differently that is,
i) 7 - 1 is a rational number because their difference is equal to 6 and it can be written in p/q form which is 6/1.
ii) 7 – 2 is also a rational number as their difference will be 5 which is a rational and can be written in p/q form which is 5/1.
So when these two rational numbers are added their sum will also be a rational number which is 11.

e) 15
Answer:
should be 12 if the x and y are squared. If you meant 2x and 2y than 12 is incorrect.
Step-by-step explanation: 144=r^2.
3x(12-8)x2)+(11-9)x3) = 14x3 the 3 is squwared tho
A=p (1+r)^t
A the amount after 16 years
P current amount 35000
R rate 0.06
T time 16 years
A=35,000×(1+0.06)^(16)
A=88,912
