Answer:
(2p + 5)(p² + 3)
Step-by-step explanation:
2p³ + 5p² + 6p + 15
take out factor p²
p² × (2p + 5) + 6p + 15
p² × (2p + 5) + 3 (2p + 5)
= (2p + 5)(p² + 3)

One length of a rectangular garden lies along a patio wall. However, the rest of the garden is enclosed by 40 feet of fencing. If the length of the garden is three times it’s width, what is the area of the garden ?
The area of the rectangular garden is determined as 192 ft² from the product of the width and length.
What is the area of the rectangular garden?The area of the rectangular garden is calculated by applying the following method.
let the width of the garden = w
then, length of the garden = 3w
The resultant length or remaining length;
= 3w - w
= 2w
The value of the width of the garden is calculated by applying the formula for perimeter of a rectangle.
2w + w + 2w = 40
5w = 40
w = 40/5
w = 8 ft
So the length of the garden = 3 x 8 = 24 ft
The area of a rectangle is calculated as follows;
Area = 8ft x 24 ft
Area = 192 ft²

Let f (x) = log2(x) + 2 and g(x) = log2(x3) – 4.
Part A: If h(x) = f (x) + g(x), solve for h(x) in simplest form. (4 points)
Part B: Determine the solution to the system of nonlinear equations. (6 points)
The function h(x) in its simplest form is [tex]h(x) = 4log_2(x)- 2[/tex]
The functions are given as:
[tex]f(x) = log_2(x) + 2[/tex]
[tex]g(x) = log_2(x^3) - 4[/tex]
(a) Function h(x)This is given as:
[tex]h(x) = f(x) + g(x)[/tex]
So, we have:
[tex]h(x) = log_2(x) + 2 + log_2(x^3) - 4[/tex]
Collect like terns
[tex]h(x) = log_2(x) + log_2(x^3)+ 2 - 4[/tex]
[tex]h(x) = log_2(x) + log_2(x^3)- 2[/tex]
Apply law of logarithm
[tex]h(x) = log_2(x \times x^3)- 2[/tex]
[tex]h(x) = log_2(x^4)- 2[/tex]
Apply law of logarithm
[tex]h(x) = 4log_2(x)- 2[/tex]
Hence, function h(x) in its simplest form is [tex]h(x) = 4log_2(x)- 2[/tex]

The number of girls int the choir is 4 times the number of boys in the choir. The total number of students in the choir is 60. How many girls are in the choir?
Answer:
15 boys in the choir
Step-by-step explanation:
60/4
4 x 15 = 60
Answer:
48
Step-by-step explanation:
First, make up some variables to represent the number of Girls and Boys in the choir.
B = number of boys
G = number of girls
You know that there are 4 times as many girls in the choir as boys. Therefore, the equation you can write is:
If you cross-multiply, then you get the simplified equation:
G = 4B
Intuitively this makes sense since if you multiplied the number of boys in the class by 4, that would be equal to the number of girls you have.
Now, we know that the total class size is 60. So girls plus boys equals 60:
G+B = 60
To solve the equation, replace the G in this equation with the replacement you found before, 4B.
G + B = 60 -->
4B + B = 60 -->
5B = 60 -->
B = 12
However, you are trying to find the number of girls, so plug the answer back into your equation.
G + B = 60 -->
G + 12 = 60 -->
G + 12 -12 = 60 - 12 -->
G = 48
The number of girls you have is 48.
In question 12 write a valid conclusion for the given set of premises or indicate that no conclusion is possible.

A triangle with vertices at point A(-2,1), B(1,5), and C(2,3) calculate the coordinates of the mid point of AB
=======================================================
Explanation:
Add up the x coordinates of A and B
-2+1 = -1
Then cut that result in half
-1/2 = -0.5
This is the x coordinate of the midpoint.
Repeat these steps for the y coordinates: (1+5)/2 = 6/2 = 3
The midpoint of segment AB is located at (-0.5, 3)
Find the coordinates of the point.
The point is seven units to the left of the y-axis and two units below the x-axis.
Answer:
(-7, -2)
Step-by-step explanation:
If you look on a graph and travel 7 units to the left of the y axis, you are traveling in the x direction (along the x axis). Since you are 7 units to the left, you are at -7 in the x direction.
If you look on a graph and travel 2 units down below the x axis, you are traveling in the y direction (along the y axis). Since you are 2 units down, you are at -2 in the y direction.
Coordinates are listed in (x,y) format, so it would be (-7, -2)

integration of sin3xsinx
Recall that
cos(x + y) = cos(x) cos(y) - sin(x) sin(y)
cos(x - y) = cos(x) cos(y) + sin(x) sin(y)
If you subtract the first equation from the second one, you end up with
cos(x - y) - cos(x + y) = 2 sin(x) sin(y)
so that
sin(3x) sin(x) = 1/2 (cos(3x - x) - cos(3x + x)) = 1/2 (cos(2x) - cos(4x))
Then in the integral,
[tex]\displaystyle \int \sin(3x)\sin(x)\,\mathrm dx = \frac12 \int(\cos(2x)-\cos(4x))\,\mathrm dx \\\\ = \frac12 \left(\frac12 \sin(2x) - \frac14 \sin(4x)\right) + C \\\\ = \boxed{\frac14 \sin(2x) - \frac18 \sin(4x) + C}[/tex]
