What is the first error Jordy made in his proof?
Choose 1 answer:
Jordy used an invalid reason to justify the congruence of a pair of sides or angles.
Jordy only established some of the necessary conditions for a congruence criterion.
Jordy established all necessary conditions, but then used an inappropriate congruence criterion.
Jordy used a criterion that does not guarantee congruence.
Answers
Answer:
D: Jordy used a criterion that does not guarantee congruence.
Step-by-step explanation:
Looking at the various steps, in step five, it says;
ΔABE ≈ ΔBCD
The reason for that is given as;
Angle - Angle - Angle congruence
Now, in test for congruence, we use any of the following criteria;
SSS: Side - Side - Side
SAS: Side - Angle - Side
ASA: Angle - Side - Angle
AAS: Angle - Angle - Side
RHS: Right angle - Hypotenuse - Side
Now, AAA was used and it's not part of the criteria to be used for congruence.
AAA is not used because it's possible for 3 angles to be equal and yet the triangles not congruent.
Thus, we can conclude that Jordy used a criterion that does not guarantee congruence.
Answer: Jordy used a criterion that does not guarentee congruence

Express g(x) as a product of linear factors.
g(x)=
Answers
Answer:
g = 7 + 13x-1 + -5x + x2
Step-by-step explanation:
Simplifying
g(x) = x3 + -5x2 + 7x + 13
Multiply g * x
gx = x3 + -5x2 + 7x + 13
Reorder the terms:
gx = 13 + 7x + -5x2 + x3
Solving
gx = 13 + 7x + -5x2 + x3
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Divide each side by 'x'.
g = 13x-1 + 7 + -5x + x2
Simplifying
g = 13x-1 + 7 + -5x + x2
Reorder the terms:
g = 7 + 13x-1 + -5x + x2

Option 2: She will randomly poll three students from each first-period class. Which statement about the methods is true? Option 1 is biased. Option 2 is biased. Neither is biased. Both are biased.
Answers
Answer:
Option 1 <3
Step-by-step explanation:
Option 1: Not everyone might be in a sports class and not everyone might be leaving at the exact same time.
Option 2: This way of collecting information is not biased because it is random and includes a wide variation of people.
Using sampling concepts, it is found that the correct option is given by:
Option 1 is biased.
What is sampling?Sampling is when a group is taken from a population to estimate a parameter or a characteristic. It has to take into account the entire population to avoid bias, which generate false results.
In this question, all students have to be considering, not just the ones who like sports practice, hence Option 1 is biased.

Answer:
D. 25% decrease
Step-by-step explanation:
When we have multiple choice questions, generally the best first step is to narrow down your options. We can see that our options are either increase or decrease. Obviously, if the class read 40 books in June and then 30 in July, that's a decrease. So option C is out of the question.
We still have three options left, so we have to now figure out the exact percentage decrease. Let's find out what percentage of 40 is 30.
[tex]\frac{30}{40}=0.75[/tex]
(Remember that percentages are parts of 1. 100%=1, 50%=.5)
So 30 is 75% of 40. And what percentage did we go down from 100%? 25%.
There was a 25% decrease in the number of books read.
I hope this helps!

A rectangle has a length of x and a width of 3x3 + 9 − x2. Find the perimeter of the rectangle when the length is 6 feet. Please HELP :(
Answers
Answer:
24
Step-by-step explanation:
A rectangle as four sides, and as we know, two of the sides equal each other. I would first start by drawing a rectangle. On one length on the outside of the triangle, put x. On the opposite congruent length, put x again since we know the sides are the same. You should have two blank sides left. On both of those sides, put 3x3 + 9 - x2 (I am assuming that you meant x squared whenever you said x2. Let me know if I assumed incorrectly. Because the length is 6, we know that x must be six. Now substitute everything that says x with the number six. Use parenthesis so you don't confuse it with other numbers. (6.) Now add everything up. You should be adding 3x3 + 9 - (6)2+ 3x3 + 9 - (3)2 + 6 + 6. Your final answer should be 24.
Then again, because this question could of meant 2x rather than x^2, this could be completely wrong, so if you take a picture of the exact question I will be able to help you better. Also, I'm not sure if your 3x3 is an x or an multiplication sign.

A rectangular field is enclosed by 600 feet of fencing what is the length and feet of the field if it's length is 10 ft more than it's width
Answers
Answer:
155 feet
Step-by-step explanation:
600 - 20= 580.
subtract 20 for the two sides of the field that are 10 feet longer than the other two sides
divided 580 by 4 to to get the length of each side of the feild (145 feet) then add 10 feel to get the length 155 feet
The length of the Rectangular field is 155 feet.
What is rectangular?A rectangle is "2D shape that has 4 sides, 4 corners and 4 right angles".
According to the question,
A rectangular field is enclosed by 600 feet of fencing. The length and feet of the field is 10ft more than field's width. so, subtract 20 feet from 600 feet.
600 - 20 = 580 feet
By definition of the rectangular, it has '4 sides' to get length of each sides of rectangular field divide 580 by 4 then we get each sides of rectangle.
[tex]\frac{580}{4}[/tex] = 125 feet.
Now, we have length of each side of the field is 145 feet. But in given question 'length of the rectangular field is 10 feet more than it's width'. So, add 10 feet to the rectangular field.
145 + 10 = 155 feet.
Hence, The length of the Rectangular field is 155 feet.
