15 + 2(2 * 4) - 4^2
= 15 + 2(8) - 4^2
= 15 + 16 - 4^2
= 31 - 4^2
= 31 - 4 * 4
= 31 - 16
= 15
Therefore, your answer is: 15
Good luck on your assignment & enjoy your day!

Answer:
A : 3n - 15 + n = 101
Step-by-step explanation:
Solution:-
- We will denote a number as "n".
- The result of 3 times itself less 15 would be:
3*itself - 15
itself = n
3*n - 15
- Then a number "n" is added to the above result:
3*n - 15 + n.
- The result of above expression is 101:
3*n - 15 + n = 101
- Option A is the correct answer
