Answer:

Step-by-step explanation:
we know that
In this problem ABCD is a rectangle
so
DC=AB
BC=AD
Let
BC ---> the length of rectangle
DC ---> the width of rectangle
we know that
The perimeter of rectangle is equal to

we have

so

simplify
----> equation A
----> equation B
substitute equation B in equation A

Solve for BC
Combine like terms

Divide by 3 both sides

<em>Find the value of DC</em>
----> 
Remember that
DC=AB
therefore

Answer:
12
Step-by-step explanation:
Answer:
y = 3x + 13
Step-by-step explanation:
Here, we want to solve for y
To solve for y, we simply are going to make y the subject of the formula
We have this as;
y - 3x = 13
y = 13 + 3x
I'm not exactly sure what you're asking but <em />I'll give it a go.
A = x -6
