Answer:
2(x - 5)(x + 4)
Step-by-step explanation:
Given
- 40 + 2x² - 2x , that is
2x² - 2x - 40 ← factor out 2 from each term
= 2(x² - x - 20) ← factorise the quadratic
Consider the factors of the constant term (- 20) which sum to give the coefficient of the x- term (- 1)
The factors are - 5 and + 4 , since
- 5 × 4 = - 20 and - 5 + 4 = - 1 , then
x² - x - 20 = (x - 5)(x + 4) and
2x² - 2x - 40 = 2(x - 5)(x + 4) ← in factored form

find the fifth term in the sequence that is defined as follows an=2(-1)^n
Answer:
-2
Step-by-step explanation:
since we're finding the fifth term, n=5
that would make the equation [tex]a_{5}=2(-1)^{5}[/tex]
we can simplify this to [tex]a_{5}=2*(-1)[/tex]
this makes [tex]a_{5}=-2[/tex]
1. If y varies inversely as x and x = 2 when y = 8, find x when y= 5.
Answer:
16/5
Step-by-step explanation:
Since y varies inversely as x, then xy = k
2(8) = 16 = k
Therefore, xy = 16
Now, 5x = 16
x = 16/5

How long will the path be.
Given:
The side of the square garden is 30ft.
To find:
The length of the diagonal of the square garden.
Solution:
We know that, the length of the diagonal of a square is
[tex]d=a\sqrt{2}[/tex] ...(i)
Where, a is the the side of the square.
We have,
Side of the square garden = 30 ft.
Putting a=30 in (i), we get
[tex]d=30\sqrt{2}[/tex]
The measure of the diagonal path is [tex]30\sqrt{2}[/tex] ft.
Therefore, the correct option is D.

The cylinder has a volume of 12pi cubic inches and a diameter of 4 inches. Find the cylinders radius and height. The cylinders radius is______ inches and it’s height is_____ inches.
Answer:
The cylinder's radius is 2 inches and it’s height is 3 inches.Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:
R = 4 in ÷ 2 = 2 in
The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H
12 = 4H
H = 3 in

Step-by-step explanation:
If you dilate a image by a factor of 2 you are multiplying each side by 2.
Side AC = Original AC x 2 = 8 x 2 = 16
Side AB = Original AB x 2 = 15 x 2 = 30
Side BD = Original BD x 2 = 8 x 2 = 16
Side CD = Original CD x 2 = 15 x 2 = 30
In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
In ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°. Find the length of f, to the nearest 10th of an inch.
=10.7
The length of f from the given triangle FGH is 10.7 inches.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² − 2bc·cosA.
Given that, in ΔFGH, g = 7.6 inches, h = 3.2 inches and ∠F=160°.
Here, f² = 7.6² + 3.2² − 2×7.6×3.2×cos160°
f² = 57.76+10.24-48.64×(- 0.9396)
f² = 68+45.70
f² = 113.7
f = √113.7
f = 10.7 inches
Therefore, the length of f is 10.7 inches.

At the bookstore, 40 copies of a popular paperback book fit perfectly on a 5-foot shelf. How many copies of this book would fit perfectly on an 8-foot shelf? A. 72 books B. 60 books C. 68 books D. 64 books
Answer:
64 books
Step-by-step explanation:
The first step is to find the number of books that will fit in the shelve per foot
= 40/5
= 8
Therefore the number of books that will fit perfectly in 8-foot shelf can be calculated as follows
= 8×8
= 64
Hence 64 books would fit in 8-foot shelf
