The given trinomial can be factored using the factorization method.
x² -12x + 35
= x² -7x -5x + 35
= x(x-7) - 5(x-7)
= (x-7)(x-5)
Thus, (x-7)(x-5) is the factored form of the polynomial.
So the correct answer is option B
He saves $ 1.75 each day from his allowance.
<u><em>Explanation</em></u>
The ratio of his savings and expenses is 7 : 5
Lets assume, his savings = 7x dollar and his expenses is 5x dollar
Given that, his daily allowance is $3. So....

So, the amount of his savings each day 
There are 2 significant figures (sig figs) which are the two '5' digits. The zeros aren't considered sig figs because we can write the number as 5.5 * 10^8 to represent the exact same idea. The 0's are simply placeholders to tell how big the number is, not necessarily how accurate it is. If the 0s were between the decimal point and a nonzero value, then the 0s would be significant. If the 0s were to the right of the decimal, then they would be significant.
Answer: 2
