Answer:
C
Step-by-step explanation:
Given
x² - 6x + 9
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the x- term (- 6)
The factors are - 3 and - 3, since
- 3 × - 3 = + 9 and - 3 - 3 = - 6, thus
x² - 6x + 9 = (x - 3)(x - 3) = (x - 3)² → C

Answer:
55 white
Step-by-step explanation:
So ratio 5:4 is essentially saying, for each 5 white marbles, there are 4 red ones. This can be represented in the equation: 5x+4x=99. We specifically want an integer solution. Because what is 1.2 of a marble? And what is -1 marbles? So as x increases by 1, the entire thing increases by 9. This gives you the equation: 9x=99 which gives you x=11. So there are 55 white and 44 red.
