To solve this problem you must apply the proccedure shown below:
1. The formula for calculate the perimeter of a rectangle is:
Where 
is the length and 
is the width.
2. The length is 
more than the width, therefore:
3. Substitute values into the formula for calculate the perimeter and solve for the width:
3. Then, the length is:
The answer is: The length is 
and the width is 
The correct answer you are looking for is 4 + 6i
Assuming that you were to simplify this, you'd get 2n + 7n + 8 = 9n + 8.
Answer:
a = 5
Step-by-step explanation:
3(a+3)+6 = 30
subtract 6 from both sides
3(a+3) = 24
divide both sides by 3
a+3 = 8
subtract 3 from both sides
a = 5
