To find the answer, I would multiply 20 by .34 and get 6.8. I would then add 6.8 to 20 and get 26.8. The cost of the DVD is $26.80.
Answer: The answer is B)
Step-by-step explanation: You wouldn't even need to draw a graph to solve this problem. Simply find the solution by adding 3 to the given x coordinate on each point and adding 5 to each y coordinate!
Using it's concept, the approximate perimeter of pentagon ABCDE is given as follows:
34.4 units.
<h3>What is the perimeter of a figure?</h3>
The perimeter of a figure is given by the sum of the lengths of it's outside dimensions.
In this problem, the vertices are in a coordinate-plane, hence the distances are found using the formula for the distance between two points.
<h3>What is the distance between two points?</h3>
Suppose that we have two points,
and
. The distance between them is given by:

The length of segment AB is:

The length of segment BC is:

The length of segment CD is:

The length of segment DE is:

The length of segment EA is:

Hence the perimeter is:
P = AB + BC + CD + DE + EA = 9.2 + 5 + 6 + 5 + 9.2 = 34.4 units.

105 ÷ (−15) = -7
15 goes into 105 seven times and then you carry the minus over.
Answer: - 2.4x^2 - 1.5x - 11.4
Step-by-step explanation:
- 4.1x^2 + 0.9x - 9.81.7x^2 - 2.4x - 1.6 = - 2.4x^2 - 1.5x - 11.4
