Answer: 
Step-by-step explanation:
The missing figure is attached.
The perimeter of a rectangle is:
Where "l" is the lenght and "w" is the width.
You can identify in the figure that:
Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:
Now you must simplify and solve for "z"
Finally, substituting the value of "z" into 
, you get:
The Answer is 9/13
Solving Steps :
3(2x-3)=-7x
6x-9=-7x
6x+7x=9
13x=9
X=9/13
Answer:
X=5
Step-by-step explanation:
Net?
I think we're being asked for the area of the shape.
2 4x4 squares and four 6x4 rectangles
2(4)(4) + 4(6)(4) = 32 + 96 = 128 square feet (that a lot of cardboard)
The statement is always true.
Let's take -.12*-.5*.2
-.12*-.5*.2=.012
And:
-.2*-.4*.3=.024
A positive multiplied by a positive is, obviously, a positive.
The result of two negative numbers multiplying together is always positive.
So, negative*negative*positive is a positive answer.
