(a-b)²=(a²-2ab+b²)

3(x-2)²-2(x-1)
=3(x²-4x+4)-2(x-1)
=3x²-12x+12-2x+2
=3x²-14x+14

Answer: 3x²-14x+14

Answer:

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

Step-by-step explanation:

You can use these Cramer's formulas to solve for x and y:

$x=\dfrac{|A_x|}{|A|},\\ \\y=\dfrac{|A_y|}{|A|},$

where

$|A|=\left|\begin{array}{cc}12&-13\\ \\17&-22\end{array}\right|\\ \\ \\|A_x|=\left|\begin{array}{cc}7&-13\\ \\-51&-22\end{array}\right|\\ \\ \\|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

So,

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

$\huge\text{Hey there!}$

$\large\text{When you hear/see the word of in mathematics, it usually means }\\\large\text{\bf multiplication. }$

$\large\text{So, when you think of think of the word \underline{of} think of its asking you to}\\\large\text{\bf multiply }$

$\large\text{Now that we got that run down out of the way lets answer your given}\\\large\text{question}$

$\large\textsf{0.25\% of 2,000}$

$\large\textsf{= 0.25\%} \times \large\textsf{2,000}$

$\large\textsf{0.25\%} = \mathsf{\bf \dfrac{25}{100}}$

$\mathsf{= \dfrac{25}{100} \times 2,000}$

$\mathsf{\dfrac{25}{100}= \bf 0.0025}$

$\large\textsf{= 0.0025} \times \large\textsf{2,000}$

$\large\text{= \bf 5}$

$\boxed{\boxed{\huge\text{Therefore, your ANSWER is: \textsf 5}}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
