Answer:

D. $( {x} - 2)^{2} = 7$

Step-by-step explanation:

$3 {x}^{2} - 12x = 9 \\ 3( {x}^{2} - 4x) = 9 \\ {x}^{2} - 4 x= 3 \\ {x}^{2} - 4x + 4 = 3 + 4 \\ {x}^{2} - 4x + {2}^{2} = 7 \\ ( {x} - 2)^{2} = 7$

Florences monthly take home pay is $5000 and her monthly rent is $900. If both her monthly and take home lay and her rent increa

max2010maxim [7]

If 5000 gets increased by 200, then you end up with 5200.

if 900 gets increased by 200, then it'd be 1100.

so in short, if we take 5200 to be the 100%, what is 1100 in percentage from it?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
5200&100\\
1100&p
\end{array}\implies \cfrac{5200}{1100}=\cfrac{100}{p}\implies p=\cfrac{1100\cdot 100}{5200}$
