4y2 + 25y + 6
The answer to 7 x 6 plus 9 is 51. You have to multiply 7 by 6 which equals 42 and add 9 onto it which equals 51.
42
I would not fully go by my answer but I think its h=6
2 + 6 * 7 = 2 + 42 = 44
4y2 + 25y + 6
(4y + 1)(y + 6)
42
3n + 4n = 42 7n = 42 n = 42/7 n = 6

2 + 6 * 7 = 2 + 42 = 44
B is -42
10y^2 -12
42 + x2 = 13x ∴ x2 - 13x + 42 = 0 ∴ (x - 6)(x - 7) = 0 ∴ x ∈ {6, 7}
