Answer: [tex]\frac{-2p^2+10p-8}{p^2-4}[/tex]
This can be written as (-2p^2+10p-8)/(p^2-4) on a keyboard.
=======================================================
Work Shown:
[tex]\frac{2p}{p^2-4} + \frac{4-2p}{p+2}\\\\\\\frac{2p}{(p+2)(p-2)} + \frac{4-2p}{p+2}\\\\\\\frac{2p}{(p+2)(p-2)} + \frac{(4-2p)(p-2)}{(p+2)(p-2)}\\\\\\\frac{2p+(4-2p)(p-2)}{(p+2)(p-2)}\\\\\\\frac{2p-2p^2+8p-8}{p^2-4}\\\\\\\frac{-2p^2+10p-8}{p^2-4}\\\\\\[/tex]
---------------------
Explanations:
In step 2, I factored p^2-4 using the difference of squares rule.In step 3, I multiplied top and bottom by (p-2) so that the second fraction has a denominator of (p+2)(p-2). We can only add fractions that have the same denominator.In step 5, I used the FOIL rule to expand (4-2p)(p-2) into -2p^2+10p-8. You can use the distribution rule or the box method as alternatives.Related Questions

Step-by-step explanation:
(6 1/4) divide by 2/3 convert the first one to a mixed fraction, 6*4 =24 +1 = 25/4
and then common denominator 2/3 = 8/12 and 25/4 = 75/12 and then 75 / 8 = 9.----- but you can only paint 9.

Answer: 105
Step-by-step explanation: Skate World offers birthday parties for a fee of $180 plus $2 per person. If you can spend no more than $210 on
your party, what is the maximum number of people who (can) attend?
The keyword "can" is telling us to basically tell us to find how much people (can) attend. Not how much will attend.

3. Kathy earns a 6% commission on every house she sells. How much
commission would Kathy make on the sale of a $650,000 house
A. $3.900
B. $39.000
C. $390,000
D. $3.900.000
Please please help
Answers
Answer:
The correct answer is Option B: $39000
Step-by-step explanation:
Given that
Price of House = P = $650000
Rate of commission = r= 6%
In order to calculate the commission amount of Kathy, we only have to calculate 6% of $650000 or by simply multiplying the price by 0.06
So,
[tex]Commission = 6\%\ of\ 650000\\=0.06*650000\\=39000[/tex]
The commission is: $39000
Hence,
The correct answer is Option B: $39000

Answer:
B>18
Step-by-step explanation:
I like to rewrite it like this:
b-8>10
Now solve:
b>18
Answer: b >18
Step-by-step explanation: add 8 to both sides .( 8+10 < b - 8+8) now you get 18 < b .But variable must go first so you put b and then flip the inequality sign to > and put 18.So now you have b >18 as your inequality.

What are the measure of reference angles according to quadrats?We have I, II, III, IV quadrants.
In quadrant I the referece angle Ф is Ф.
In quadrant II the referece angle Ф is (π - Ф).
In quadrant III the referece angle Ф is (π + Ф).
In quadrant IV the referece angle Ф is (2π - Ф).
We know π is equal to 180°.
The conversion of radian to degrees is we multiply the radian value by 180°/π.
Given, The radian measure is 5π.
Therefore, the equivalent degree measure is,
= (5π)×(180/π).
= (5×180)°.
= 900°.

How many feet of fencing will the homeowner need to build the dog pen?
38 + 4V2

38 + 1072
Answers
Answer: the answer is C 52
Step-by-step explanation:
The length of the fencing needed is given by the lengths of the lines
that goes around the space she wants to fence shown in the graph.
Correct response:
The amount of fencing the homeowner needs is; 38 + 10·√2Methods used to find the length of fencing neededThe coordinates of the vertices of the fenced area are presented as
follows;
A(-7, 7), B(4, 7), C(6, -7), and D(-7, -7)
Therefore, by finding the distance between the given points, we have;
Length of AB = 4 - (-7) = 11
Length of AD = 7 - (-7) = 14
Length of CD = 6 - (-7) = 13
Length of BC = √((6 - 4)² + (-7 - 7)²) = [tex]\sqrt{200}[/tex] = 10·√2
Length of fencing needed, L = AB + AD + CD + BC
Which gives;
L = 11 + 14 + 13 + 10·√2 = 38 + 10·√2
The length of fencing needed, L = 38 + 10·√2Learn more about the distance between points given the coordinates here:

1.) To solve this you must first know the formula for area of a rectangle:Area [tex]=\sf{H}[/tex] × [tex]\sf{W}[/tex]Area [tex]=7x^4y^2z[/tex] × [tex]2xy^5z^{14}[/tex]Note:
- It doesn't matter which measurement fills the height or width part in the formula.
Equation at the end of Step 1:
[tex]7x^4y^2z[/tex] × [tex]2xy^5z^{14}[/tex][tex]2xy^5z^{14}[/tex] × [tex]7x^4y^2z[/tex]2.) Add 4 and 1, (x powers:)[tex]x^4+x=x^5[/tex]Note:
- To multiply powers of the same base, you can add their exponents. So you just do [tex]4+1=5[/tex].
- When you have a plain variable like [tex]x[/tex], you can assume [tex]x=1[/tex].
Equation at the end of Step 2:

simplify 2x4 a_3 =16a÷8 1_a
Answers
Answer:
(a+2) (a-18)
Step-by-step explanation:
Factoring a2-16a-36
The first term is, a2 its coefficient is 1 .
The middle term is, -16a its coefficient is -16 .
The last term, "the constant", is -36
Step-1 : Multiply the coefficient of the first term by the constant 1 • -36 = -36
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .
-36 + 1 = -35
-18 + 2 = -16 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2
a2 - 18a + 2a - 36
Step-4 : Add up the first 2 terms, pulling out like factors :
a • (a-18)
Add up the last 2 terms, pulling out common factors :
2 • (a-18)
Step-5 : Add up the four terms of step 4 :
(a+2) • (a-18)
Which is the desired factorization
