Answer:
2n + 4 = 4nStep-by-step explanation:
Twice a number n → 2 · n = 2n
Twice a number n plus 4 → 2n + 4
The product of 4 and a number n → 4 · n
Twice a number n plus 4 is the product of 4 and a number n → 2n + 4 = 4n

Write the equation of the graph shown below in factored form.
F(x) = (x - 1)^2(x - 1)(x + 3)
Ofb) = (x - 1)^2(x + 1)(x - 3)
Answer: A) f(x) = (x − 2)^2(x + 1)(x − 3)
Step-by-step explanation: The graph shows the zeros to be -1, +2 (multiplicity 2), and +3.
When b is a zero, (x-b) is a factor. Then the factors of the function shown are ...
f(x) = (x -(-1))·(x -2)·(x -2)·(x -3)
f(x) = (x -2)^2(x +1)(x -3)

The answer to the question is -4/5
What is the solution to the linear equation: 2/5+p=4/5+3/5p
Answer:
p = 1
Step-by-step explanation:
2/5 + p = 4/5 + 3/5p
2/5 + p = 3p/5
2/5 + p = (4 +3p)/5
2 + 5p = 4 + 3p
5p = 4 + 3p - 2
5p = 3p + 2
5p - 3p = 2
2p = 2
p = 1
Please mark me the brainliest!?!
Answer: C. P = 1
Step-by-step explanation: Plug in 1 to the both p variables on both sides, and you will get the same answer for each equation.

If a sphere with diameter d is inscribed in a cube with side length e, what is the relationship between d and e?
Answer:
d = e
Step-by-step explanation:
An inscribed sphere in a cube will have a diameter equal to the edge length of the cube:
d = e
__
The distance between the faces of the cube is the same as the edge length.
a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?
Answer:
a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?
Step-by-step explanation:
Cost minus the charge which is 8 dollars minus 5.50 is the difference in which you divide 80 by it. 8-5.50= 2.5. 80 divided by 25 = 32. Hope this is the answer you're looking for.

Refer to picture below:
Answer/Step-by-step explanation:
Perimeter of a right triangle : 3 units , 5 units, 4 units
Perimeter = 3 + 4 + 5 = 12
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Surfaces of a three-dimensional figure: 5ft, 7 ft, 3 ft
Surfaces area: 2(7*3)+2(7*5)+2(3*5)
= 142 square feet
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Volume of a three-dimensional figure: 4m , 10 m , 3 m
Volume = 10 * 4 * 3 = 120 cubic meter
~Lenvy~
Answer:
Step-by-step explanation:
Perimeter of a triangle = sum of 3 sides
= 3 + 4 + 5
= 12 units
Surfaces of a three-dimensional figure = sum of 3 pairs of surfaces
= 5*7*2 + 7*3*2 + 3*5*2
= 70 + 42 + 30
= 142 square fts
Volume of a three-dimensional figure = length*width*height
= 4*10*3
= 120 m^3

The radius of a circle is 12 meters. What is the circle's area
Answer:
452.16 m²
Step-by-step explanation:
Given :-
Radius = 12 m
To Find :-
Area
Formula Required :-
Area (circle) = πr²
Solving :-
Area = 3.14 x 12 x 12
= 3.14 x 144
= 452.16 m²
Solution :-
452.16 m²
Answer:
144
Step-by-step explanation:
A=πr^2
Where:
A
is the Area of the Circle: what we are solving for in this problem.
r
is the Radius of the Circle: 12 meters for this problem
Substituting and calculating
A
gives:
A=π(12)^2m^2
A=π144m^2
A= 144m^2
This circle would have an area of 144 square meters.

Solve for x in the circle below. Show your work, equations, and mark your answer.
Answer:
x = -8
Step-by-step explanation:
The sum of arcs of a semicircle is 180°. That means the arc whose measure is -11x+12 has a measure of 180° -80° = 100°.
-11x +12 = 100
-11x = 88 . . . . . . subtract 12
x = -8 . . . . . . . divide by -11
So what is the answer to this x+2=7+8
Answer:
x = 13
Step-by-step explanation:
x = 7 + 8 - 2
x = 7+6 = 13

In the above figure, m∠A = 30° and m∠B = (2x + 10)°. If angles A and B are complementary angles, what are the value of x and the measure of angle B?
A.
x = 55, m∠B = 60°
B.
x = 25, m∠B = 60°
C.
x = 70, m∠B = 150°
D.
x = 25, m∠B = 50°
Answer:
Step-by-step explanation:
option B
Complementary angles add up to 90°
m∠A + m∠B = 90
30 + 2x + 10 = 90
2x + 40 = 90
To find the value of x, we have to isolate x. To isolate x, first we have subtract 40 from both sides.
2x = 90 -40
2x = 50
Now, divide both sides by 2
x = 50/2
x = 25°
∠B = 2x + 10
= 2*25 + 10
= 50 + 10
∠B = 60°

The volume of the vase obtained by revolving the curve y=2+sinx from x=0 to x=5 about the x-axis is 80.115 unit³
What is volume?
Volume is the amount of space occupied by a three dimensional shape or object.
The volume V is given by:
[tex]V=\pi \int\limits^0_5 {(R^2-r^2)} \, dx \\\\R = 2+sinx;r=0, hence:\\\\V=\pi \int\limits^0_5 {(2+sinx)^2} \, dx\\\\V=80.115\ unit^3[/tex]

Answer:
t₁ = 14
d = -2
Step-by-step explanation:
Given :-
t₆ = 4
t₁₀ = -4
To Find :-
t₁ and d
Solving :-
t₆ = t₁ + 5d = 4 -(1)
t₁₀ = t₁ + 9d = -4 -(2)
(2) - (1)
4d = -8
d = -2
t₁ + 5(-2) = 4
t₁ = 14

Find the perimeter of the figure below, in feet
(Note: Diagram is NOT to scale)
Answer:
56.6 ft
Step-by-step explanation:
→ Perimeter = All sides added together
5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6
Answer:
56.6
Step-by-step explanation:
Perimeter is just adding all the outer value of an shape
So we add all the answers
5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6
but there is easier way
5.2 x 2 = 10.4
7.7 x 6 = 46.2
10.4 + 46.2 = 56.6
at the end don't forget to add "ft"
Answer = 56.6 ft

The scatter diagram shows information about 10 cars.The 10 cars are the same type and make.
Another car is 4 years old and has been valued at £2600.
A)Show this information on the graph.
B) describe the relationship between the age and the value of the cars.
A car of the same type and make is 3 1/2 years old
C) estimate the value of the car
Answer:
a) you need to plot a cross on the graph (with the pencil) in the right place:
(x-axis: 4, y-axis: 2600)
b) the older the car is, the lower its value. there is a negative correlation between the cars age and its value.
c) you need to draw a line of best fit on the graph. where the line is at 3 1/2 years, that is its estimated value. (my guess is around £3000)

Carlos and his friends are going to out to bowl, eat dinner, and see a movie. The starts at 8:10 p.M. And they want to arrive 20 minutes before it starts. They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater. At what time should they plan to leave Carlo's house?
Answer:
They should leave Carlo's house by 4:20 PM
Step-by-step explanation:
The movie starts at 8:10 pm, they want to arrive 20 minutes before the movie starts
20 minutes before 8:10 pm = 7:50 pm.
Hence, they should arrive by 7:50 pm
Duration of their activities before the movie is calculated as:
They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater.
: 1 hour + 1 hour 15 minutes + 20 minutes + 45 minutes + 10 minutes
= 2 hour 15 minutes + 75 minutes
= 2 hour 15 minutes +1 hour 15 minutes
= 3 hours 30 minutes in total.
The time they are meant to leave is calculated as:
7:50 pm - 3 hours 30 minutes
= 4:20pm
