Lets call the perimeter P and the length of the rectangle l.  The first figure is a square with side length 2x + 2 so P = 4(2x + 2) = 8x + 8.  For the rectangle, P = 2l + 2(x + 3) = 2l + 2x + 6.  These values both equal P so they must equal each other.  8x + 8 = 2l + 2x + 6.  Now we have to solve for l.  

8x + 8 = 2l + 2x + 6  
8x + 2 = 2l + 2x
6x + 2 = 2l
3x + 1 = l

Based on the diagram shown, all of the following are true statements except
ira [324]

You are correct. The answer is choice C.

The other choices A, B, D have each side add up to 180 degrees either because the angles are a linear pair (adjacent and supplementary) or because the angles are same side interior angles. Same side interior angles are supplementary if a transversal line cuts through a pair of parallel lines as so happens in this diagram.

Write an equation of the line passing through the points. Write the equation in general form.
Reika [66]

Answer: y=2x+8

Step-by-step explanation:

(2,12)=(x1,y1)

(-7,-6)=(x2,y2)

(y2-y1)/(x2-x1)=(-6-12)/(-7-2)=-18/-9=2=m

y=mx+b

y=2x+b

insert (2,12) to y=2x+b

12=2*2+b

12=4+b

8=b

y=2x+8

8x-11+5x+2x+6=180 what is the measurement for x.
Verizon [17]

I assume you're looking for the value of x?

Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180

Add 5 to both sides: 15x=185

Divide both sides by 15: x=12 1/3

So x is 12 1/3 or 37/3

Hope this helped!
