Answer:
80 Cubic Units
Step-by-step explanation:
5 x 4 = 20
20 x 4 = 80
Hope it helps :)
The room is a square, meaning all four sides are 20ft long.
Because we know all the side lengths, we can find the perimeter of the square by adding the side lengths together.
(20 + 20 + 20 + 20) = 80
Now that we know the perimeter, we have to match this number to the feet of crepe paper.
We can find this by dividing the total length needed by the length a single roll provides.
80 / 8 = 10
Therefore, we know that Katie will have to buy a minimum of 10 rolls if she wants to cover the entire perimeter of the room.
Hope this helps! :)
First, you need to see which number all of these numbers have in common, and that is number 4. So, let's start:
-4(x2 - 4x + 6)
The expression in the brackets cannot be factored further, which means that the answer above is the complete factor of the original expression. Hope it helps. :)
Answer:

Step-by-step explanation:
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or 
Let
y-------> the interest earned on an account
x------> the balance in the account
step 1
Find the constant k of proportionality
For 

substitute the values

The equation is

step 2
Find the amount of interest earned on an account with a balance of $500
so
For
substitute in the equation and solve for y
