Answer:
1. transversal: (of a line) intersecting a system of lines.
2. acute angle: Acute angles measure less than 90 degrees. Right angles measure 90 degrees. Obtuse angles measure more than 90 degrees. Learn about angles types and see examples of each.
3. alternate extirior angles: When two lines are crossed by another line (called the Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal.
4. congruent: in agreement or harmony.
5. congruent figures: Congruent figures are geometric figures that have the same shape and size. That is, if you can transform one figure into another figure by a sequence of translations , rotations , and/or reflections , then the two figures are congruent.
6. isosceles triangle: In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case
7. obtuse angle: An obtuse angle ...” ... An obtuse angle has a measurement greater than 90 degrees but less than 180 degrees. However, A reflex angle measures more than 180 degrees but less than 360 degrees. So, an angle of 190 degrees would be reflex.
8. right angle: an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
9. remote interior angle: Remote interior angles are angles that don't share a vertex or corner of a triangle with the exterior angle. The measure of the exterior angle equals the sum of the two remote interior angles.
10. same-side interior angles:Same side interior angles are two angles that are on the same side of the transversal and on the interior of (between) the two lines. Same Side Interior Angles Theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary.
11. corresponding angles: When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. Example: a and e are corresponding angles. When the two lines are parallel Corresponding Angles are equal.
12. corresponding parts: corresponding parts. Sides or angles that occupy the same relative positions in similar polygons. congruent triangles. 2 triangles are congruent if and only if all pairs of corresponding sides and angles are congruent.
13. equilateral angle: In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
14. exterior angle: 1 : the angle between a side of a polygon and an extended adjacent side. 2 : an angle formed by a transversal as it cuts one of two lines and situated on the outside of the line.
15. scalene triangle: A scalene triangle is a triangle in which all three sides have different lengths. Also the angles of a scalene triangle have different measures. Some right triangles can be a scalene triangle when the other two angles or the legs are not congruent.
16. similar figures: Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal. This common ratio is called the scale factor .
17. striaght figures: A line that does not curve. In geometry a line is always straight (no curves).
18. theorem: a general proposition not self-evident but proved by a chain of reasoning; a truth established by means of accepted truths.

Step-by-step explanation:
Both equations use x squared
Answer:
The common facor is x-3.
Step-by-step explanation:
The first expression can be factored with a difference of squares, x+3 and x-3. You can check that by multiplying them together to get x²-9. Knowing that you need a common factor, one that works for both expressions, you can immediately eliminate A and B. The second expression, x²-5x+6, has to share one of these two factors. To factor this, you find the numbers that multiply to the c term and add to the b term. (Ax²+bx+c) so b is -5 and c is 6. All you have to do is find out which two numbers add to -5 and multiply to 6. You start with factors of 6, which are +-6 and +-1, and +-3 and +-2. Say you try 6 and 1 first. The b term is negative, so these two added have to add to a negative number, which means positive 6 and positive 1 won´t work. The only way to add to -5 is to add 1 to -6 or -6 to 1, but multiplying those together gives you -6, and you need positive 6 in the c term. That leaves you with -2 and -3. they add to -5, and multiply to -6, which means that your common term is x-3. Test this by expanding your result, (x-2)(x-3), if you get the original expression theyre both factors.

Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?
Write a system of equations.
Answers
Answer:
Look at the attachment
Step-by-step explanation:
There are 12 children tickets did the group buy.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The group bought 20 admission tickets for $340.
And, Adult tickets cost $20, and children’s tickets cost $15.
Let number of children = x
And, Number of adult = y
Hence, We get;
The system of equations are,
x + y = 20
y = 20 - x .. (i)
And, 15x + 20y = 340
3x + 4y = 68 .. (ii)
Substitute the value of y from (i) in (ii);
3x + 4(20 - x) = 68
3x + 80 - 4x = 68
80 - 68 = x
x = 12
Thus, There are 12 children tickets did the group buy.

Our bases in this problem are 60.5 and 75.5. We are going to addd these together and we’re going to get, 136.
Now, we must multiply 136, by its height(16). 136 x 16 = 2176.
Lastly we are going to divide by 2 and get our final answer of 1088 feet cubed.

Answers
Divide the sale price by the percentage of the original cost.
Percent of original cost = 100% - 52% = 48 %
158.40 / 0.48 = 330.00

Read the excerpt from an interview with Florence Griffith-Joyner.
WILL: I know that you dropped out of college in 1979 to help support your family. It seems like family must be very important to you.
FLORENCE GRIFFITH-JOYNER: Yes. Family is first in my life. It was a very difficult decision for me to drop out of college at that time. Growing up in poverty, I didn't have the financial support that I would have needed to go to college. I wasn't offered an athletic scholarship. I wasn't offered an academic scholarship. I thought, "How am I going to stay in school?" So I enrolled in school, and I thought, "I really want to run, but I know I have to concentrate on my academics as well." I tried a year of college, and I thought, "I can't continue because I have no financial support." I had to take the bus two hours to school, two hours back. The need was greater than what I could afford.
What is the purpose of the interviewer’s question?

Answer:
A: 479.94/6
B: D, 56.79
C: 79.99 and 56.79
D: Obviously 79.99 is greater than 56.79 so the slope in question A is greater than the slope in B (C)
Step-by-step explanation:
Question A:
For this one we will let x= nights in a hotel and y=cost
We can then just pick two points on the table and plug in the numbers to the formula above
Let's pick the first and last one
our two ordered points are (0,20) (6,499.94)
We can plug this in and get
(499.94-20)/(6-0) which simplified to 479.94/6
Question B:
This equation is in slope intercept form
Slope intercept form is as follows
y=mx+b
where m is the slope and b is the y intercept
we can see that the m value is 56.79 which means D is the answer
Question C:
This is pretty easy
First divide 99.8/2 and get 49.9 and the other answer is just 56.79
Answer:
A: 479.94/6
B: D, 56.79
C: 79.99 and 56.79
D: Obviously 79.99 is greater than 56.79 so the slope in question A is greater than the slope in B (C)

Answer:

Step-by-step explanation:
25+15=40
2y=40
40/2=20

Answer:
y = 20
Step-by-step explanation:
25=2y - 15
2y - 15 = 25
2y - 15 + 15 = 25 + 15
2y = 40
2y ÷ 2 = 40 ÷ 2
y = 20
__________________________
2y - 15 = 25
2(20) - 15 = 25
40 - 15 = 25
25 = 25
