shutvik [7]

Answer:

5 containers high

Given that :

Given :

Width = 20 containers

Length = 50 containers

Total containers = 5000

Hence,

Total containers = width * length * height

5000 = 20 * 50 * height

5000 = 1000 * height

Height = 5000 / 1000

Height = 5 containers

The variables A, B, and C represent polynomials where A=x^2, B=3x+2, and C=x-3. What is AB-C^2 in simplest form?
yuradex [85]

Answer:

AB-C^2 = 3x^3 + x^2 + 9

Step-by-step explanation:

Hi

AB = (x^2)*(3x+2)= 3x^3 + 2x^2

C^2= (x-3)^2 = x^2 - 9

So

AB-C^2 = 3x^3 + 2x^2 - x^2 + 9 = 3x^3 + x^2 + 9

Which expression is equivalent to -0.55 – 0.47a + a?
Leto [7]

Answer:

-0.55 + 0.53a

Step-by-step explanation:

              -0.55 – 0.47a + a

 To find an expression equivalent to this, we must simplify the equation to a reasonable extent;

         -0.55 – 0.47a + a

      = -0.55 + 0.53a

      = 0.53a - 0.55

The expression equivalent to the given one is -0.55 + 0.53a  or 0.53a - 0.55

What is the slope of the line
cupoosta [38]

Answer:

I believe the slope would be -2

Step-by-step explanation:

The line goes <u>down 2</u> boxes and <u>over 1</u> box before it intersects with another point.  Knowing slope = \frac{rise}{run}, we know that slope = \frac{-2}{1} which is equal to -2.
