123
Step-by-step explanation:
b.2+7
We have that
If you draw a diagram, and draw perpendiculars from the intersection to the sides of the rectangle, you will see they are the mid point of each side.
see the attached figure
<span>If the mid point of the smaller side is ---------> x.
The mid point of the larger side will be -----------> (x + 4) </span>
The full length if the smaller side will be 2x and the length of the larger side will be 2(x + 4) = 2x + 8
The perimeter = 2 times the length + 2 times the width.
2(2x + 8) + 4x = 56
4x + 16 + 4x = 56
8x = 40
x = 5
Therefore
length = 2x + 8 = 18cm
<span>width = 2x = 10cm
</span>
the answer is
<span>the lengths of the sides of the rectangle are
</span>
length = 18cm width = 10cm

it’s B
Step-by-step explanation:
just took the test

2x+y=-6 the equation has to be in slope form (y=mx+b) the first thing that you have to do is find the slope which you can do fairly easy by moving the 2x to the other side of the equation. Y=-2x-1 then you use that slope and use a different y intercept for the two lines to be parallel
