Answer:
The length of the rectangle is 9 cm
Step-by-step explanation:
Given: The length of rectangle(l) = (x+3) cm and a width of rectangle (w) = 
cm a
Also, perimeter of rectangle is 24 cm.
Perimeter of rectangle is to add the lengths of all the four sides.
Perimeter of rectangle (P) is given by;
P=2(l+w)
Substituting the value of P = 24 cm , l = (x+3) cm and w =
then,
Divide by 2 both sides of an equation;
Combine like terms;
Subtract 3 from both the sides we get;
Simplify:
Multiply both sides by 
we get
Therefore, length of rectangle(l) = (x+3) = 6+3 = 9 cm

Step-by-step explanation:
There are about 
stars in the universe.
The Milky Way galaxy
stars.
All we need to do to find the number of galaxies is to divide the total number of stars in the universe by the number of stars in the Milky Way:
Number of galaxies = (Number of stars in the universe) / (Number of stars in the Milky Way)
Number of galaxies = 
N = 
N = 
The number of galaxies in the universe is approximately .
