Does anyone know the answer to this!?

PolarNik [594]

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,

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

Factor the expression completely over the complex numbers: 25x2 +144

Paha777 [63]

Answer:

25x² + 144 = (5x + 12i) (5x - 12i).

Step-by-step explanation:

We have to factorize the expression 25x² + 144, using the complex number.

Now, $i = \sqrt{- 1}$ can be treated as the complex number as there is negative value with in square root.

So, $i^{2} = - 1$

Therefore, we can write the original expression as

25x² + 144

= 25x² - (i²)(144)

= (5x)² - (12i)²

= (5x + 12i) (5x - 12i)

So, the factorization is 25x² + 144 = (5x + 12i) (5x - 12i). (Answer)

Anit [1.1K]

Answer:

28.26658805 (I included every digit in case your teacher needs you to round)

Step-by-step explanation:

In order to find x, we need to isolate x by subtracting 15^2 and taking the square root of both sides.

Thus, we have:

$15^2+x^2=32^2\\x^2=32^2-15^2\\\sqrt{x^2} =\sqrt{(32^2-15^2)} \\\sqrt{x^2}=\sqrt{799} \\x=28.26658805$
