The volume of a single layer in a rectangular prism is 18 cubic centimeters. There are 5 layers in this rectangular prism. What
sweet [91]

Answer: 90cm^3

Step-by-step explanation:

A rectangular prism is a three-dimensional solid.

A rectangular prism has six faces (each one of these faces are rectangles), eight vertices and twelve edges.

You know that this rectangular prism has 5 layers and the volume of one of these layers is 18 cubic centimeters (18cm^3).

Assuming that all these layers are equal, the volume of this rectangular prism can be calculated with:

V_{prism}=5*V_1

Where V_1 is the volume of one layer.

Substituting, you get:

V_{prism}=(5)(18cm^3)\\\\V_{prism}=90cm^3

Which statement about the function is true?
krok68 [10]

Answer:

The function is negative for all real values of x where -6< x < -2

Step-by-step explanation:

Given f(x) = (x + 2)(x + 6)

The graph of the function is as shown in the attached figure.

As shown, we can deduce the following:

The function is positive for all real values of x where x > -2 and x < -6

The function is zero at x = -2 and x = -6

The function is negative for all real values of x where -6 < x <-2

Compare the observations to the given statements:

So, The true statement is The function is negative for all real values of x where -6 < x <-2
