Answer : 3 or 4
Let the number be represented by n.
12 + n2 = 7n : n2 - 7n + 12 = 0
This equation can be factored.
(n - 3)(n - 4) = 0
Then either n - 3 = 0, when n = 3 ; or n - 4 = 0, when n = 4
CHECK : 12 + 32 = 12 + 9 = 21 = 7 x 3
12 + 42 = 12 + 16 = 28 = 7 x 4.
4
The number is 3 or 4.
3 or 4.
128
12y
4
The number is 3 or 4.
3 or 4.
7, because multiplying the same sqaure root cancels them.

Twelve times seven equals 84.
12y
The question is ambiguous and the two possible answers are: Twelve times (a number and 5 times the number) = 12*(n + 5n) = 12*6n = 72n Twelve times a number amd five times the number = 12*n + 5*n = 17*n
43/12=3.5833. Or, three times with a remainder of seven.
