Answer:
[tex]\frac{(x + 1)(x - 2)}{x^{2} + 5}[/tex] This is the third option.
Step-by-step explanation:
Dividing a fraction is the same as multiplying the reciprocal of the second fraction.
[tex]\frac{x + 1}{x + 4}[/tex] × [tex]\frac{(x + 4)(x - 2)}{x^{2} + 5}[/tex]
[tex]\frac{(x + 1)(x + 4)(x - 2)}{(x + 4)(x^{2} + 5)}[/tex] Here, we can just get rid of the (x + 4) because it is common in both the numerator and denominator so they cancel each other out.
So the answer would be [tex]\frac{(x + 1)(x - 2)}{(x^{2} + 5)}[/tex] .
I hope this makes sense!! ^-^
can somebody help!! fastest and correct answer gets brainly!
Answer and Step-by-step explanation:
We know that the triangle got dilated by a scale factor of 4. This means that the sides are multiplied by 4.
So 6 becomes 24, and 8 becomes 32.
Now, we find the area of the triangle.
24 × 32 = 768
768 ÷ 2 = 384.
The answer is D. 384 square cm.
The answer IS NOT B. 96 square cm, because you don't multiply the area of the triangle before the dilation. The dilation occurs first, and then you have to find the area.

2 sin^2 (x) + 3 sin (x) + 1 = 0
help me find the solution
Answer:
Step-by-step explanation:
\[2~ sin^2 x+3sin x+1=0\]
\[2sin^2x+2sin x+sin x+1=0\]
2sinx(sin x+1)+1(sin x+1)=0
(sin x+1)(2 sin x+1)=0
either sin x+1=0
sin x=-1=sin 3π/2=sin (2nπ+3π/2)
x=2nπ+3π/2,where n is an integer.
or 2sin x+1=0
sin x=-1/2=-sin π/6=sin (π+π/6),sin (2π-π/6)=sin (2nπ+7π/6),sin (2nπ+11π/6)
x=2nπ+7π/6,2nπ+11π/6,
where n is an integer.
An even number is divisible by 2.
if - then :
hypothesis:
conclusion:
Answer:
A logical sentence is written as:
If P, then Q.
Where:
P = hypothesis
Q = conclusion.
For this particular case, we know that a number is even only if the number is divisible by 2.
Then we can write:
if a number is divisible by 2, then it is an even number.
Here we have:
hypothesis = a number is divisible by 2.
conclusion = the number even.

Rewrite the fraction in the sentence below as a percentage.
In 2010, a fire destroyed
3/10 of the farmer's crops.
Answer: 30%
Step-by-step explanation:
Method 1:
The original fraction is [tex]\frac{3}{10}[/tex]
To convert to a percent, the denominator should be equal to 100 (since percent is per 100)
Multiply the top and bottom by 10
[tex]\frac{3}{10} * \frac{10}{10} = \frac{30}{100}[/tex]
Since the numerator is 30, 3/10 as a percent is 30%
Method 2:
The original fraction is [tex]\frac{3}{10}[/tex]
To convert to a percent, first convert the fraction to a decimal (do 3 ÷ 10)
0.3
10 | 3 0
-30
-------------
0
You get 0.3
Now multiply the decimal by 100
0.3 * 100 = 30
30%
Method 3:
The original fraction is [tex]\frac{3}{10}[/tex]
[tex]\frac{3}{10} = \frac{x}{100} \\10x = 300\\x = 30[/tex]
cross-multiply to solve the equation
30%

Suppose a book has been on a desk 1 m above the floor. A student accidentally knocks the book off of the desk and it falls to the floor. During this process, ___________ energy has been changed into _______ energy.
Answer: Potential; Kinetic
Step-by-step explanation:
''...During this process, potential energy has been changed into kinetic energy.''
Potential energy is the energy that a stationery object has because it is stored within the object. In this case the object is the book.
When an object begins to move, it gains kinetic energy which is converted from its potential energy. As the book falls to the floor in this scenario, it gained kinetic energy as its potential energy was converted to enable it move.
There is a line that includes the point (3, 3) and has a slope of 4. What is its equation in
slope-intercept form?
Answer:
y = 4x - 9Step-by-step explanation:
The equation in point-slope form with slpope of m and including point (x₁,y₁) is:
y - y₁ = m(x - x₁)
m = 4
(3, 3) ⇒ x₁ = 3, y₁ = 3
So:
y - 3 = 4(x - 3) ← the point-slope form
y - 3 = 4x - 12 {add 3 to both sides}
y = 4x - 9 ← the slope-intercept form
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary) 210,206,202,... Find the 35th term.
Answer:
u1 = 210
u2 = 206 = u1 - 4
u3 = 202 = u2 - 4
........
un = u1 - 4(n - 1) = 214 - 4n
so the 35th term is 214 - 4.35 = 214 - 140 = 74

The difference between two numbers is 308328.If the smaller number is
6524, what is the larger number?
-(2) maths
Answer:
Let get small number is x and large number is y.
The difference between two numbers is 308328.
ie. y- x = 308328.
If the smaller number is
6524.
So, x= 6524.
Hence,
y - x = 308328
y- 6524 = 308328
y = 308328 + 6524
y = 314852

Answer:
the median should be 2.5
Answer:
2.5
Step-by-step explanation:
By taking the dots ploted on the graph we can take those as actual numbers and put them on a line.
0, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 5
Now you will take off the numbers until you get to the middle number
0, 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 5
Because the middle two numbers are 2 and 3, you take the mean of the two numbers.
(2 + 3) / 2
= 2.5
