Which of the following is the product of the rational expressions shown below?
Answer:
(3x^2+6x)/(x^2-16)
Step-by-step explanation:
When multiplying fractions you just go straight accross
this means that our fraction is equal to
((x+2)(3x))/((x-4)(x+4))
The numerator is quite easy 3x(x+2)=3x^2+6x
The second one is a little tough at first and if you need help I would reccomend using khan academy
but pretty much you get x^2-16
put them together and get your answer

plz help me out. branliest whoever gets it right
Answer:
True!
Step-by-step explanation:
If an object travels at a constant speed, then the distance traveled is directly proportional to the time spent traveling, with the speed being the constant of proportionality. The circumference of a circle is directly proportional to its diameter, with the constant of proportionality equal to π.

The price of a notebook was $3.60 yesterday. Today, the price fell to $3.10. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
13.9%
Step-by-step explanation:
First, we find the amount of decrease.
$3.60 - $3.10 = $0.50
The price decreased $0.50.
Now we find what percent $0.50 is of $3.60.
percent = part/whole * 100%
percent = $0.50/$3.60 * 100%
percent = 0.13888 * 100% = 13.9%
Answer: 13.9%
Line a passed through points (-2,1) and (2,9). Which is parallel to line a?
Answer:
D
Step-by-step explanation:
Line A's slope: 9-1/2+2 = 8/4 = 2
y = 2x+b
y = 2x-5
If the slope of 2 lines are equal, then the lines are parallel.
f(x)= (x-1)(x(x+1)+2x) find all rational zeros
Answer:
x = 0, x = 1, x = - 3
Step-by-step explanation:
To find the zeros, let f(x) = 0 , that is
(x - 1)(x(x + 1) + 2x) = 0 ← distribute and simplify parenthesis
(x - 1)(x² + x + 2x) = 0
(x - 1)(x² + 3x) = 0 ← factor out x from the second parenthesis
x(x - 1)(x + 3) = 0
Equate each factor to zero and solve for x
x = 0
x - 1 = 0 ⇒ x = 1
x + 3 = 0 ⇒ x = - 3
Millie expected 20 friends to show up to her birthday party, but 24 attended. What was
her percent error? Round to the nearest percent.
Answer:
Her percent error was: ≈ 17% (whole percent)
Step-by-step explanation:
Given
Approximate value = 20 friends
Exact Value = 24 friends
To determine
Percent error
Using the formula to calculate the Percent error
Percent error = | Approximate Value| - Exact Value | / | Exact value | × 100
= | 20 - 24 | / | 24 | × 100
= | - 4 | / | 24 | × 100
Apply absolute value: |-a| = a, a>0
= 4/24 × 100
= 16.67 %
≈ 17% (whole percent)
Thus, her percent error was: ≈ 17% (whole percent)

At an art auction, Geannina's painting sold for over $ 300 $300dollar sign, 300. Write an inequality that describes P PP, the price of Geannina's painting in do
Answer:
[tex]P > 300[/tex]
Step-by-step explanation:
Given
An art sold for over $300
Required
Represent as an inequality
Represent the price with p.
This implies that; P is over 300
In inequalities; the term "over" means greater than i.e. >
Hence:
P is over 300 is equivalent to [tex]P > 300[/tex]

35
A-
C
What is the measure of x?
Answer:
x = 145
Step-by-step explanation:
x and 35 are adjacent angles and are supplementary, sum to 180° , then
x + 35 = 180 ( subtract 35 from both sides )
x = 145

Answer:
5^12
Step-by-step explanation:
When you have a power to the power, you multiply the powers. Since we have (5^3)^4, we can multiply the powers because we have a power to the power. Since 3 * 4 is equal to 12, we have 5^12. That means that 5^12 is the answer.

Also please don't answer if you don't know!! Thanks in advance
Answer:
JML=142 degrees
Step-by-step explanation:
This shape is a rhombus, as all 4 sides are equal, but the angle measures are not. One of the properties of a rhombus is that opposite angles are congruent, and adjacent angles are supplementary. Only the second one is important. Since angles KLM and angle JML are supplementary, the equation KLM+JML=180 can be used. KLM is then substituted by the given angle measure, 38 degrees, to get an equation such as JML+38=180. Now, to solve for JML, 38 must be subtracted from both sides of the equation, which leaves teh answer of JML=142.
Al, Tom and Joe share €3000.
The ratio of the amount Al gets to the amount Tom gets is in the
ratio 5:4
Joe gets 1.5 times the amount Tom gets.
Work out the amount of money that Tom gets.
Answer:
Tom's share = €800
Step-by-step explanation:
Given that:
Amount shared by Al, Tom and Joe = €3000
Ratio of Al's share to Tom's share = 5 : 4
Joe's share = 1.5(Tom's share) = 1.5(4) = 6
Therefore,
Ratio of Al, Tom and Joe = 5 : 4 : 6
Let,
x be the number of times of amount each get.
5x + 4x + 6x = 3000
15x = 3000
Dividing both sides by 15
[tex]\frac{15x}{15}=\frac{3000}{15}\\x=200[/tex]
Tom's share = 4x = 4(200) = €800
Hence,
Tom's share = €800

Answer: 35. The equation would be y = 17/2x
Answer:
32) yes, linear
33) no
34) yes
Step-by-step explanation:
32) if you look at the difference in the y-values and the difference of the x-values you will see that they all equal 3; for example, 24/8, 21/7, 18/6
33) following same method as for #32, there is not a consistent ratio of change between x-and-y values
34) yes, constant ratio is 10
Given the circumference of a circle is 8π centimeters, calculate the area of the circle in terms of π.
Answer:
16π cm²
Step-by-step explanation:
circumference = 2πr
Area = πr²
We need to determine r to calculate the area
2πr = 8π
Divide both sides of the equation by 2π to find r
r = 4
Now, we determine area.
area = πr² = π4² = 16πcm²
Answer:
[tex]\Large\boxed{\sf{16\pi\text{cm}^2}}[/tex]Step-by-step explanation:
The formula for the circumference of a circle can be used to solve this problem.
[tex]\underline{\text{CIRCLE OF A CIRCUMFERENCE FORMULA:}}[/tex]
[tex]:\Longrightarrow: \sf{C=2\pi r}[/tex]
[tex]\text{AREA:}= \sf{\pi r^2}[/tex]
[tex]\sf{2\pi r=8 \pi}[/tex]
You have to divide by 2 from both sides.
[tex]\sf{\dfrac{2\pi r }{2}=\dfrac{8\pi}{2} }[/tex]
Solve.
Divde the numbers from left to right.
8/2=4
r=4
[tex]\sf{\pi r^2=\pi4^2}[/tex]
Solve by exponents.
[tex]\sf{4^2=4*4=\boxed{\sf{16}}[/tex]
[tex]\Longrightarrow: \boxed{\sf{16\pi \text{cm}^2}}[/tex]
Therefore, the correct answer is 16πcm².I hope this helps. Let me know if you have any questions.
