16x2 - 56x + 49 = (4x - 7)2
7d + 2 < 51 7d < 49 d < 7
349
49 plus 10 equals 59.
-x2+14x=49
(x2 + 14x + 49) = (x + 7)2
49 + 49 + 49 + 49 + 49 = 245 OR 49*5=245
Applying the rules of BODMAS, 48 + 45 + 2 + 49 + (1/5) = 144.2
The answer for 2 over 7 plus 2 over 5 is: 24/49 or 24 over 49

9t2 + 42t + 49 is a perfect square, equal to (3t + 7)2
2x2 + 21x + 49 = (2x + 7)(x + 7)
i hope you mean (2x^2 + 21x + 49) you cant solve it its already in its lowest possible form
x2 - 14x + 49 = (x - 7)2
16x2 - 56x + 49 = (4x - 7)2
49 plus 49
