I’ll give points + brainalist
Answer: 8x^2+72x+81
Step-by-step explanation:
Hi! I'm not sure if my answer is correct, but please check! Hope it helps.
First the rectangles area is l x w = (3x+7)(4x+8) = 12x^2+52x+56
Because there is a square cut out, we need to find the area of the square and subtract that from the area of the rectangle.
Square Area: (2x+5)(2x+5)= 4x^2+20x+25
Subtract the two areas: 12x^2+52x+56 - 4x^2+20x+25
Which would simplify to 8x^2+72x+81

Darnell went to the movie theater with his friends. The movie theater started at 2:35 pm and lasted 1 hour 45 minutes. What time did the movie end?
If the movie started at 2:35 and lasted 1 hour
Answer: 4:20 pm
Step-by-step explanation:
We know that the movie started at 2:35 and lasted 1 hour and 45 minutes. We can split the time that it lasted into the hour and the 45 minutes to make things easier, since 1 hour after 2:35 is simply 3:35.
From here, we can add the extra 45 minutes. We can do this by first finding out how many minutes were left in that hour. There are 60 minutes in 1 hour, and 60 - 35 = 25 minutes
45 - 25 = 20
after adding the 25 minutes to complete the hour (4:00), we have 20 minutes left
4:00 + 0:20 = 4:20
Which function has the following characteristics? • A vertical asymptote at x = 3 • A horizontal asymptote at y = 2 Domain: {** +3] 2x - 8 X - 3 y=x2-9 2 9 x² - 4 4 OB. V C. 2x2 - 18 x² - 4 4 2x2 - 8 O D. ** - 9
SOLUTION
To get this, note that the vertical asymptote can be gotten by setting the denominator to be equal to 0.
If we do this, we will notice that the vertical asymptote of option A and option D is x = 3
That is
for option A
[tex]\begin{gathered} y=\frac{2x-8}{x-3} \\ x-3=0 \\ x=3 \end{gathered}[/tex]For option D
[tex]\begin{gathered} y=\frac{2x^2-8}{x^2-9} \\ x^2-9=0 \\ x^2=9 \\ x=3 \end{gathered}[/tex]So, the answer is either option A or D.
But to get the correct answer, let us look at the graphs for both functions
Graph of A
[tex]y=\frac{2x-8}{x-3}[/tex]From the graph, you can see that the domain is defined at x = 3. Notice that the green line cut across x = 3.
Now let's check Graph of option D
[tex]y=\frac{2x^2-8}{x^2-9}[/tex]From the graph, you can see that the domain is defined at x = -3 and x = 3. Notice that the purple and green line cut across x = -3 and x = 3. So, the domain here is
[tex]x=\pm3[/tex]Hence

( 14 + 2 ) 2 0 = 5 + 4 0 what type of property is this?
The question provides the relationship as shown below:
[tex](\frac{1}{4}+2)20=5+40[/tex]If we solve both sides individually, we have the left-hand side to give
[tex](\frac{1}{4}+2)20=45[/tex]and the right-hand side to give
[tex]5+40=45[/tex]Since both sides give the same result, we can attempt to manipulate the left-hand side of the equation with a common property we are familiar with: The Distributive Property.
The Distributive Property is written out as shown below:
[tex]a(b+c)=(a\cdot b)+(a\cdot c)[/tex]Applying this rule to the left-hand side, we get:
[tex]\begin{gathered} (\frac{1}{4}+2)20=\frac{1}{4}\cdot20+2\cdot20 \\ =5+40 \end{gathered}[/tex]This is the same expression present on the right-hand side of the equation.
Therefore, the property illustrated is the DISTRIBUTIVE PROPERTY.

Which of these systems of equations could be used to choose a ticket plan ?
Answer:
A. y = 0.50x + 12
y = 1.25x
Explanation:
The equation that model the total cost of plan A is:
y = 12 + 0.50x
Because there is a cost of $12 that is independent of the number of rides x and there is a cost of $0.5 for each ride.
In the same way, the equation that model the total cost of plan B is:
y = 1.25x
Because there is only a cost of $1.25 for each ride.
Therefore, the system of equations that could be used to choose a ticket plan is:
A. y = 0.50x + 12
y = 1.25x

4x² + 3x - 2
This is a quadratic trinomial
Explanation: A quadratic equation has 2 as its highest index power
Then a polynomial involving 3 terms is a trinomial equation.
Hence the expression
4x² + 3x - 2 has its highest index power as 2 (4x raised to the power of two) and it has three separate terms, and that makes it a quadratic trinomial.

Looking at the given inequality,
pi/8 = 0.392
pi/4 = 0.7
46% = 46/100 = 0.46
2/5 = 0.4
square root of 0.25 is 0.5
Therefore, the values of x that would the inequality are 0.46 and 0..4
Therefore, the correct options are C and D

Explanation
[tex]18x^2=-21x[/tex]Step 1
to get the form
[tex]ax^2+bx+c=0[/tex]a) add 21 x in both sides
[tex]\begin{gathered} 18x^2=-21x \\ 18x^2+21x=-21x+21x \\ 18x^2+21x=0 \\ so\text{ a=18, b=21, c=0} \end{gathered}[/tex]Step 2
now, factorize the left hand side of the equation
[tex]\begin{gathered} 18x^2+21x=0 \\ (x)(18x+21)=0 \\ so\text{, the factors are x and (18x+21)} \end{gathered}[/tex]now, to get zero from those factors
[tex]\begin{gathered} (x)(18x+21)=0 \\ x=\text{ 0} \\ or \\ 18x+21=0 \\ \text{subtract 21 in both sides} \\ 18x+21-21=0-21 \\ 18x=-21 \\ \text{divide both sides by 18} \\ \frac{18x}{18}=\frac{-21}{18} \\ x=-\frac{21}{18}=-\frac{7}{6} \\ x=-\frac{7}{6} \end{gathered}[/tex]so, the answer is

Four of the locations used the same number of notepads per department, but the Northwest and Central offices used fewer notepads per department. The graph shows that the Northwest location used the same number of notepads as the Southeast location overall. If the Northwest location used fewer notepads per department, which of the following could be the number of departments for the Northwest location?
So we plot the values over the bars
Now we identify that each line is separated by 2
Answer: Then we get central as 8 and northwest as 6
Part A: Clancey and Ethan are starting new books. So far, Clancey has read 1/4 of his book, which has 240 total pages and Ethan has read 2/5 of his book, which has 170 total pages. Who has read more pages so far, Clancey or Ethan?Of the combined total number of pages in both books, what fraction have clancey and ethan read combined?
In order to find who has read more pages, let's find the number of pages read by each one.
The number of pages read by Clancey is:
[tex]\frac{1}{4}\cdot240=\frac{240}{4}=60[/tex]The number of pages read by Ethan is:
[tex]\frac{2}{5}\cdot170=\frac{340}{5}=68[/tex]So Ethan read more pages.
The combined number of pages in both books is 240 + 170 = 410.
The combined number of pages read is 60 + 68 = 128
So the fraction is:
[tex]\frac{128}{410}=\frac{64}{205}[/tex]please explain steps to get correct answer in pic below
Let's use the properties of the sum:

To simplify this we use the properties listed below:
[tex]\sum ^n_{i\mathop{=}1}na_i=n\sum ^n_{i\mathop{=}1}a_i[/tex][tex]\sum ^n_{i\mathop{=}1}(a_i+b_i)=\sum ^n_{i\mathop{=}1}a_i+\sum ^n_{i\mathop{=}1}b_i[/tex][tex]\sum ^n_{i\mathop{=}1}c=cn[/tex]Each angle of the equilateral triangle in the figure has measure (2x – 9)°. Determine the value of x.Question options:A) x = 69B) x = 34.5C) x = 25.5D) x = 60
On an equilateral triangle, each angle has a measure of 60º. Then:
[tex]2x-9=60[/tex]Solve for x. To do so, add 9 to both sides of the equation:
[tex]\begin{gathered} \Rightarrow2x-9+9=60+9 \\ \Rightarrow2x=69 \end{gathered}[/tex]Divide both sides of the equation by 2:
[tex]\begin{gathered} \Rightarrow\frac{2x}{2}=\frac{69}{2} \\ \Rightarrow x=34.5 \end{gathered}[/tex]Therefore, the value of x is:
[tex]34.5[/tex]Solve for x. 70° 37° 10x + 3x=
Let's suppose, the given equation is:
37 = 10x + 3
By solving it
37 - 3 = 10x
34 = 10x
34/10 = x
x = 17/5
Hence, the value of x is 17/5.
How to graph it I know others one but not this one
Answer: (0, 2)
Explanation
The coordinates are a set of values that show the exact position of a point. In graphs, it is usually a pair of points in the form (x, y), where x represents the value in the horizontal axis and y represents the value of the vertical axis.
As we can see from the image above, in our point x = 0 (marked in red) while y = 2 (marked in purple). Rearranging the coordinate we get (0, 2).
26 is what % of 65.
Suppose that 65 is the 100%, then we can find the percentage that is 26 from 65 using a rule of three:
[tex]\begin{gathered} 65\rightarrow100\% \\ 26\rightarrow x\% \\ \Rightarrow x=\frac{26\cdot100}{65}=\frac{2600}{65}=40 \\ x=40\% \end{gathered}[/tex]therefore, 26 is 40% of 65
