Answer:
D. 6x + 3
Step-by-step explanation:
A perimeter is just the sum of all sides of a shape.
First, write an equation to add all sides of the triangle:
(x + 4) + (3x - 2) + (2x + 1)
What is inside the parentheses is all already simplified. Also, it is addition, so the order in which we add does not matter. So, we can now get rid of the parentheses and combine like terms:
x + 3x + 2x + 4 -2 + 1
6x + 3
And that's our final answer: 6x + 3

9 1/3 / 2/3
9 1/3 = 28/3
28/3 / 2/3
28/3 x 3/2
84/6

she needs 14 bags
You can see that the area of the blue rug is 2*2 or 4. The area of the rug needed to cover the stain will have to be 4*4 or 16. This means that the original rug will need to be dilated by 4 to cover the stain (4 (original) times 4 = 16 (new))
The sum of the angles of 4-sided shapes is 360°
To find the missing angle, you can do this:
x + 92° + 47° + 82° = 360° Add 92, 47, and 82 together
x + 221° = 360° Subtract 221 on both sides to get "x" by itself
x + 221° - 221° = 360° - 221°
x = 139° Your answer is the 4th option
Answer:
There is enough evidence at the 0.05 significance level that the percentage is less than 25%.
Step-by-step explanation:
<em>The question has no options. However, there are enough details to arrive at a conclusion.</em>
<em></em>
Required
What can we conclude about the claim of the publisher.
From the question, we understand that the null hypothesis is rejected.
In statistics, a hypothesis is rejected, if the level of significance is less than the required or determined value.
In this case, the determined value 25% and the level of significance is 0.05
<em>So, the conclusion on the claim is that there is enough evidence at the 0.05 significance level that the percentage is less than 25%.</em>
