Andre has a dog pen in the shape of a rectangle.
The perimeter of his dog pen is 60 feet.
The length of his dog pen is twice its width.
What is the area of Andre’s dog pen?
Answer:
So for number 1 and 2
Step-by-step explanation:
Perimeter is = 2(L+W)
L=2w as it said on the problem above.
60=2 (2w+w)
60= 2 (3w)
60 = 6w
w= 10 , L=20 P=60
Area of rectangle = L x W
20 x 10 = 200

The focus of a parabola is (-6, -3). The directrix of the parabola is y =4.
What is the equation of the parabola?
o y = - a (x + 6)? +
o y = - (x + 6)+
o y = - + (x + 1)² +6
y = -5(x - ) - 6

well, we know the directrix is at y = 4 and the focus point is down below it at (-6 , -3), meaning is a downward opening vertical parabola, like the one you see in the picture below.
keeping in mind that the vertex is equidistant from the directrix and focus point by a distance "P", that puts this vertex at ( -6 , 1/2 ), and since the parabola is opening downwards, P is negative.

Product of polynomials can be done by distribution of multiplication over addition. The product of [tex](2x - 3)(2x^2 + 7x - 1)[/tex] is [tex]4x^3 + 8x^2 -23x + 3[/tex]
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
[tex]a(b + c) = a\times b + a\times c[/tex]
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
The product result of the given expression is
[tex](2x - 3)(2x^2 + 7x - 1) = 2x(2x^2 + 7x - 1) -3(2x^2 + 7x - 1) \\(2x - 3)(2x^2 + 7x - 1) = 4x^{1+2} + 14x^2 -2x - 6x^2 - 21x + 3\\(2x - 3)(2x^2 + 7x - 1) = 4x^3 + (14 -6)x^2 + (-2 -21)x + 3\\(2x - 3)(2x^2 + 7x - 1) = 4x^3 + 8x^2 -23x + 3[/tex]
It is because when bases are same and there is multiplication, then powers add up, so we have: [tex]a^b \times a^c = a^{b+c}[/tex]
Also, we've
[tex](-ve \times (+ve) = -ve\\(-ve) \times (-ve) = +ve\\(+ve) \times (+ve) = +ve\\(+ve) \times (-ve) = -ve[/tex]
where -ve, +ve are sign of operands and result.
That's why [tex]2 \times -1 = -2[/tex]
Thus,
The product of [tex](2x - 3)(2x^2 + 7x - 1)[/tex] is [tex]4x^3 + 8x^2 -23x + 3[/tex]

Answer:
I believe the answer is B. 15/5 = n/12
Step-by-step explanation:
Once again same method as I've explained before. However, this one tricked me a little bit and still is because of the appearance of the smaller triangle. However, If I don't focus on that I believe this answer is correct. This is because in order to find the missing side we need to find the factor of which the triangle was expanded. So we must divide a given side of the bigger triangle by the same similar side of the little triangle, like 15/5. Then we must divide n by its similar side which the appearance made me think 13 which is not an option so I believe it is 12 and it was just trying to throw me off. So n/12. Therefore that is why I believe B is correct.

Multiplying binomials by polynomials btw
Answer:
2n³ - 3n² - 7n + 3
Step-by-step explanation:
Hi there! Don't worry, polynomials seem hard but you will get them with practice.
I am going to show you 2 methods of multiplying polynomials. These methods are universal, or they work with any polynomial multiplication problem:
Method 1: Distributive PropertyThis is perhaps the most common method. You distribute 1 value to another or multiply each and every single term.
Let's solve it!
(n² - 3n + 1)(2n + 3)n²(2n + 3) - 3n(2n + 3) + 1(2n + 3) n²(2n) + n²(3) - 3n(2n) - 3n(3) + 2n + 3 See how I distributed the values?2n³ + 3n² - 6n² - 9n + 2n + 3Now, we add up like terms. Like terms should have the same coefficient and should be raised to the same power.
2n³ + 3n² - 6n² - 9n + 2n + 3 2n³ - 3n² - 7n + 3There you have it! This is how you solve with The distributive Property Method.
Method 2: Area ModelThis is the next universal method, Area modeling.
Area models can be set up by the number of terms we have. In the first polynomial we have three terms:
n²-3n+1Just for this method, keeping the positive signs helps.
For the binomial, we have two terms (hence, binomial)
2n+3We set up our are model like this, with the terms laid out as side lengths of a rectangle. (Attachment "A")
Next, we find the area of each individual tile. (Attachment "B")
Now, we add like terms. Something nice about area models is that most of the time, the like terms are matched up in a diagonal. (Attachment "C")
2n³ + 3n² - 6n² - 9n + 2n + 3 2n³ - 3n² - 7n + 3We end up with the same answer as before.

What is 40% of a circle of radius 225 feet
Answer:
About 63,617 ft²
Step-by-step explanation:
[] The area of a circle is equal to πr²
π(225)² ≈ 159,043
[] To find 40%, we can multiply our whole by 40%
-> 40% divided by 100, 0.4, becomes a decimal
159,043 * 0.4 = 63,617
-> Don't forget to add on the units once you are done, this problem was done in feet, since it is an area we used feet squared

Diane left a 15% tip for a meal costing $44. What was the amount of the tip? $2. 93 $3. 41 $5. 90 $6. 60.
The amount left by Diana is percent part of total food cost. The 15% tip of $44 total cost given by Diana is : Option D: $6.60
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Since the total food cost was $44 and the tip was 15% of the total cost, thus,
[tex]\text{Tip amount} = \dfrac{44}{100} \times 15 = 6.6 \text{\:dollars}[/tex]
Thus,
The 15% tip of $44 total cost given by Diana is : Option D: $6.60

The given polynomial can be rewritten as factors of the common ratio of
the geometric progression.
Response:
If a, b, c, d are in GP, (a² + b² + c²) × (b² + c² + d²) = [tex]\underline{(a\cdot b + b \cdot c + c\cdot d)^2}[/tex]
Which method can be used to analyze the given polynomial relation?The assumed parameters are;
a, b, c, and d for a geometric sequence
Therefore;
[tex]\mathbf{\dfrac{b}{a}} = \dfrac{c}{b} = \dfrac{d}{c} = r[/tex]
Which gives;
b = a·r
c = b·r
d = c·r
Therefore;
c = b·r = a·r²
d = c·r = a·r³
(a² + b² + c²) × (b² + c² + d²) = (a² + (a·r)² + (a·r²)²) × ((a·r)² + (a·r²)² + (a·r³)²)
(a² + a²·r² + a²·r⁴) × ((a²·r²) + (a²·r⁴) + a²·r⁶) = a⁴·r²·(r⁸ + 2·r⁶ + 3·r⁴ + 2·r² + 1)
Which gives;
a⁴·r²·(r⁸ + 2·r⁶ + 3·r⁴ + 2·r² + 1) = a²·r·(r⁴ + r² + 1) × a²·r·(r⁴ + r² + 1)
a²·r·(r⁴ + r² + 1) × a²·r·(r⁴ + r² + 1) = (a²·r·(r⁴ + r² + 1))²
a²·r·(r⁴ + r² + 1) = a²·r⁵ + a²·r³ + a²·r
a²·r = a·b
a²·r³ = b·c
a²·r⁵ = c·d
Therefore;
a²·r⁵ + a²·r³ + a²·r = a·b + b·c + c·d
(a² + b² + c²) × (b² + c² + d²) = (a²·r·(r⁴ + r² + 1))² = [tex]\underline{(a\cdot b + b \cdot c + c\cdot d)^2}[/tex]

An electrician bought 120 feet of electrical wire and used 105 feet of it. What percent of the wire went unused? 15% 12. 5% 8. 75% 7%.
Answer:
12.5%
Step-by-step explanation:
105 is what percent of 120?
you can use this proportion:
if/of = %/100
in this problem:
is = 105
of = 120
'what percent' = p/100
105/120 = p/100
cross-multiply to get:
120p = 10500
p = 10500/120
p = 87.5
So the electrician used 87.5%, out of 100%, meaning 12.5% went unused
Answer:
The percent of the wire that went unused was 15%.
Step-by-step explanation:
You can set up these equations:
Turn 15% into 0.15
12.5% into 0.125
8.75% into 0.0875
7% into 0.70
Now, the number of wire unused is 15. Since 120 - 105 = 15. So, we can set up these equations to see which percentage it was that got unused:
0.15 x 120 = 18
0.125 x 120 = 15
0.0875 x 120 = 10.5
0.70 x 120 = 84
So, the answer is 15%.
