Answer:

12

Step-by-step explanation:

We know that AD=BC and that AB=CD. We also know the perimeter of the rectangle ABCD to be 54 units.

From this, we can add up the sides which will be equal to 54 units.

AD+BC+AB+CD=54

2x+2x+3x-3+3x-3=54

10x=60

x=6

Since we are trying to find the length of side BC we substitute this value back into 2x.

BC=2x =2*6=12

Therefore, the length of BC is 12 units.

Write an equation of the line that passes through the point (4, –5) with slope 2.
Igoryamba
So, the equation is y=mx + b and you want to solve for b to find the y intercept. 
-5=2(4) + b
-5=8+b
subtract the 8 
-13=b
the equation is y = 2x - 13
