\\\\\\
\textit{now then, what is }sin(~~sin^{-1}(1)~~)?\textit{ is just }1\\\\
-------------------------------\\\\

\bf likewise\qquad 
\begin{cases}
cos(~~cos^{-1}(whatever)~~)\implies  whatever\\
sin(~~sin^{-1}(whatever)~~)\implies  whatever\\
tan(~~tan^{-1}(whatever)~~)\implies  whatever\\
cot(~~cot^{-1}(whatever)~~)\implies whatever\\
sec(~~sec^{-1}(whatever)~~)\implies  whatever\\
csc(~~csc^{-1}(whatever)~~)\implies  whatever
\end{cases}

so, surely you know what that is then.

<h3>Answer:  B) 2</h3>

=========================================================

Explanation:

Take away the four white small squares on the left side. To balance things out, you have to add 4 black squares to the right side.

Also, take away the two white long rectangles from the right side. To balance this out, you have to add 2 gray long rectangles to the left side.

You should have:

  • 5 gray rectangles, and no squares (of any color) on the left side
  • 10 black squares, no long rectangles (of any color), on the right side

From here you'll group up the 10 black squares so that you'll have 2 black squares per gray rectangle.

This means the solution is 2.

-------------------------------------

If you're curious about the algebraic way to solve, then you could do this:

3x-4 = -2x+6

3x+2x = 6+4

5x = 10

x = 10/5

x = 2

This method doesn't require us to use the visual model.
