which products result in difference of squares
(x-y)(y-x)
(6-y)(6-y)
(3+xz)(-3+xz)
(y^2-xy)(y^2+xy)
Answer:
[tex](3+xz)(-3+xz)[/tex]
[tex](y^2-xy)(y^2+xy)[/tex]
Step-by-step explanation:
The Difference of Squares
Any difference of two squared monomial results in a factored form like shown below:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
Similarly:
[tex](a-b)(a+b)=a^2-b^2[/tex]
For a product of binomials to be a difference of squares, they must be in the described form.
------------------------
(x-y)(y-x) can be rewritten as:
-(x-y)(x-y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(6-y)(6-Y)
Since both binomials are identicals, the product will not result in a difference of squares.
-----------------------
(3+xz)(-3+xz) can be rewritten as:
(xz+3)(xz-3). This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](3+xz)(-3+xz)=(xz)^2-9[/tex]
-----------------------
[tex](y^2-xy)(y^2+xy)[/tex]. This product is a sum multiplied by a difference of the very same terms, thus the result is a difference of squares:
[tex](y^2-xy)(y^2+xy)=y^4-(xy)^2[/tex]
-----------------------
Summarizing:
(3+xz)(-3+xz)
[tex](y^2-xy)(y^2+xy)[/tex]
the sum of a number and 6 is the same as the number times 11.

Ashley opened a lemonade stand on her street. It costs her $12.50 to buy the supplies each day, and she sells lemonade for $2.50 a cup. If she wants to make at least $200.00 in profits (sales - expenses) each day, what is the minimum number of cups of lemonade Ashley needs to sell? Input your answer as a whole number.
Answer:
x= 75
Step-by-step explanation:
Subtract sales - expenses
200 - 12.5 = 187.5
2.5x = 187.5
Divide by 2.5 on both sides
187.5/2.5
x = 75
A coat was originally priced at $80. It went on sale for $70.40. What was the percent that the coat was discounted?
Answer:
12%
Step-by-step explanation:
(80 - 70.40)/80 * 100 = 12
4. Emily ate dinner at Geisha. Her total was $17.50. A 8% sales tax was
added to her bill. After, Emily added a 20% tip on the total after tax. What
was Emily's final total?
*
Answer: $22.68
Step-by-step explanation:
17.50 times 0.08 = 1.40
17.50 + 1.40 = 18.90
Now the tip:
18.90 times .2 = 3.78
18.90 + 3.78 = 22.68

Find the measure of the angle indicated in bold.
Answer:
125°
Step-by-step explanation:
16x - 3 = 14x + 13 (vertical angles)
16x - 14x = 13 + 3
2x = 16
x = 16/2
x = 8
(16x - 3)° = (16*8 - 3)° = (128 - 3)° = 125°

Which of the following sets of numbers have the same mean, median, and mode?
0 3,5,8, 4.5
O 5, 1, 2, 2.5
10.6.4, 2.8
2.68.6.3
Step-by-step explanation:
calculate the each one then compare
hint :
mean : add all the numbers and divide by how many numbers there are .
median : the middle number . for example : 12345 . 3 is the middle number .
mode : the number that appears more often than the other numbers.

If MI = 15 m, SM = 20 m, and TM = 9 m, what is the value of RM?
Answer:
RM=12m
Step-by-step explanation:
You can set up a proportion of 9/15 on one side and RM/20 on the other. you would then cross multiply and solve for RM
the distance between the two points rounding to the nearest tenth
(-8,-6) and (-3,-4)
Answer:
5.4
Step-by-step explanation:
To find the distance between two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], plug them into the following equation:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(-3-(-8))^2+(-4-(-6))^2}[/tex]
Two negatives make a positive
[tex]d=\sqrt{(-3+8)^2+(-4+6)^2}\\d=\sqrt{(5)^2+(2)^2}\\d=\sqrt{25+4}\\d=\sqrt{29}\\d=5.4[/tex]
Therefore, the distance between the two points rounded to the nearest tenth is 5.4.
I hope this helps!
