Answer:they all equal 69
Step-by-step explanation:
You must know that the sum of interior angles is 180°. We also know that AC and BA are congruent which means angles B and C are also congruent. To find x we can assume 25=5x. Which makes x=5, and angle C=25°.
Then we can add all the angles to find y and A. 25+25+(3y+70)=180. Then solve for y and then solve for angle A.
Answer:
x^2 - 2xy + y^2.
Step-by-step explanation:
(x - y)^2
= (x - y)(x - y)
= x(x -y) - y(x - y)
= x^2 - xy - xy + y^2
= x^2 - 2xy + y^2.

It would be best to list this values in the data set given, from least to greatest:
________________________________________________
{ 3, 3, 3, 3, 4, 5, 5, 6, 9 } .
________________________________________________
The mode is the number that occurs most frequently in the data set, which is: "3".
_________________________________________________________
{The number, "3", occurs FOUR (4) times. The number, "4", occurs ONE (1) time. The number, "5", occurs TWO (2) times. The number, "6", occurs ONE (1) time. The number, "9", occurs ONE (1) time.}.
___________________________________________________
The range is calculated from subtracting the LOWEST value in the data set FROM the HIGHEST value in the data set.
____________________________________________________
The lowest values in the data set is: "3" .
The highest value in the data set is: "9" .
________________________________________________
To calculate the range: 9 <span>− 3 = 6 . The range is: "6".

Answer:
The expression to determine the total cost in dollars is 
.
Step-by-step explanation:
Given:
Service charge to make a photo book = $20
Cost per extra page = $0.75
Cost to ship the complete photo book = $5
We need to write expression to determine the total cost in dollars.
Solution:
Let the number of extra pages be denoted by 'x'.
Also Let the Total cost be denoted by 'y'.
Now we can say that;
Total cost will be equal to sum of Service charge to make a photo book and Cost per extra page multiplied by number of extra pages and Cost to ship the complete photo book.
framing in equation form we get;
Hence the expression to determine the total cost in dollars is .
