Answer:
<h2>The answer is option C</h2>
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
l = 9 cm
w = 6 cm
Substitute the values into the above formula and solve
We have
P = 2(9) + 2(6)
= 18 + 12
We have the final answer as
<h3>P = 30 cm</h3>

Answer:
   13.8654599313 and -0.8654599313
Step-by-step explanation:
If one of the numbers is x, then the other is 13-x, and their product is ...
   x(13 -x) = -12
   x^2 -13x = 12 . . . . multiply by -1 and simplify
   x^2 -13x +6.5^2 = 12 +6.5^2 . . . . complete the square
   (x -6.5)^2 = 54.25
   x -6.5 = √54.25
   x = 6.5 +√54.25 ≈ 13.8654599313
and the other number is ...
   13 -x = 13 -13.8654599313 = -0.8654599313
The two numbers are 13.8654599313 and -0.8654599313.
