Answer:

3 = 12

Explanation:

9 * (9+1) = 9 * 10 = 90

8 * (8+1) = 8 * 9 = 72

7 * (7+1) = 7 * 8 = 56

6 * (6+1) = 6 * 7 = 42

---------------------------

Optional Steps (for bigger numbers):

Hence, the formula is

a = b(b+1)

= b² + b

----------------------------

Hence,

3 * 4 = 12

Hence,

3 = 12

Hope this helps and be sure to have a wonderful time ahead! :D
