The answer is 21 + 4x.


You find this answer by adding up all the sides.
9+12+4x= 21+4x ... you don't add 4x because it has a variable that we do not know of the value.

Answer:

A linear function has the form y=mx+b

A line has a proportional relationship if y/x is always the same ratio for any value.

The slope m=(y2-y1)/(x2-x1) for some two points on a line is always constant, else it wouldn't create a line.

A line won't be proportional if you adapt b because the ratio of y/x won't match the slope anymore.

In the end this means all lines with proportional relationships must intersect (0,0) or in other words f(0)=0.

This happens if they have the shape y=mx.

Prove that x-y = √(x+y)^2-4xy?
Svetlanka [38]

Proved Below

\Longrightarrow x-y = \sqrt{(x+y)^2-4xy}

\Longrightarrow x-y = \sqrt{x^2+2(x)(y)+ y^2-4xy}

\Longrightarrow   x-y = \sqrt{x^2+2xy-4xy+y^2}

\Longrightarrow x-y = \sqrt{x^2-2xy+y^2}

\Longrightarrow x-y = \sqrt{(x-y)^2}

\Longrightarrow x-y =x-y
