Choose the correct simplification of the expression ( 4x/y)^2.

erik [133]

$\large\displaystyle\text{$\begin{gathered}\sf \left(\frac{4x}{y}\right)^{2} \end{gathered}$}$

To raise 4x/y to a power, raise the numerator and denominator to the power, and then divide.

$\large\displaystyle\text{$\begin{gathered}\sf \frac{(4x)^{2} }{y^{2} } \end{gathered}$}$

Expand (4x)².

$\large\displaystyle\text{$\begin{gathered}\sf \frac{4^{2} x^{2} }{y^{2} } \end{gathered}$}$

Calculates 4 to the power of 2 and gets 16.

$\boxed{\large\displaystyle\text{$\begin{gathered}\sf \frac{16x^{2} }{y^{2} } \end{gathered}$} }$

Which equation does the graph represent?

Art [367]

Answer:

It is the second answer

Step-by-step explanation:

The standard form of an ellipse is

x^2/a^2 + y^2/b^2 or x^2/b^2 + y^2/a^2 = 1

If the x is the main axis we use the first form. If the y is the main axis we use the second form. We will use the second form.

our a is 3 and our b is 4

x^2/3^2 + y^2/4^2

Simplify the expression (4x - 3)(x + 5).

Drupady [299]

(4x-3)(x+5)
= 4x^2+20x-3x-15
= 4x^2+ 17x -15.

The final answer is 4x^2+ 17x -15~
