Answer 1

Is there a picture? @PeepzStudyTime

Answer 2

@lloio thnx :) @iGreen Nope theres no pic

Answer 3

Okay, well the square's gonna look something like:

Answer 4

@iGreen its a rectangle :(

Answer 5

@iGreen not a square but anyway how to do it

Answer 6

xD

It's okay.

Answer 7

@iGreen XP

Answer 8

Okay, these are congruent so we can write:

\(4x - 16 = 2(x + 2)\)

Distribute the 2 into the parenthesis:

\(4x - 16 = 2x + 4\)

Add 16 to both sides:

\(4x = 2x + 20\)

Subtract 2x to both sides:

\(2x = 20\)

Divide 2 to both sides:

Can you finish it?

Answer 9

Well it's going to be:

\(x = 10\)

Answer 10

We can plug this back into the equation:

\(2x + 4\)

\(2(10) + 4\)

\(20 + 4\)

\(24\)

So the whole length is 24.
