Answer:
244 cm³
Step-by-step explanation:
Step 1: Given data
Height of the prism with a pentagonal base (h): 8 cm
Area of the pentagonal base (A): 30.5 cm²
Step 2: Calculate the volume of the prism with a pentagonal base
We have a regular pentagonal prism, that is, the 5 sides of the base are equal and we know the area of the base and the height of the prism. We can calculate its volume using the following expression.
V = A × h
V = 30.5 cm² × 8 cm = 244 cm³
For this case we have the following inequality:

To find the solution we follow the steps below:
We apply distributive property on the right side of inequality:

Adding 13 to both sides of the inequality we have:

We subtract 6x on both sides of the inequality:

Thus, we have that any value of "x" makes the inequality fulfilled. Thus, the solution is given by all real numbers.
Answer:
The solution set is (-∞,∞)
Answer:
(3·x + 6) + (7·x + 4) = 180 --> x = 17
3·17 + 6 = 57
Answer D is correct.
