Answer:
(x+9)(x+3)
x*x = x^2
x*3 = 3x
9*x = 9x
9*3 = 27
Answer = <em><u>x^2 + 12x + 27</u></em>

Let the numerator = x. Then,
The fraction is x/(3x+4).
If both the numerator and denominator are increased by 4, the fraction will be (x+4)/(3x+8), which, according to the question is equal to 9/25. So,
(x+4)/(3x+8) = 9/25
25(x+4) = 9(3x+8)
25x + 100 = 27x + 72
2x = 28
x = 14
Thus, the numerator is 14 and the denominator is (3*14 + 4), which is equal to 46. So the fraction is 14/46.
it would be adding by 2's because to get from 2 to 4 you have to add two or from 6 to 8 you have to add two also
