Answer: x^2 + 4x + 4
Step-by-step explanation:
Answer:
x^2 + 4x + 4
Step-by-step explanation:
We can do this first
(x + 2)^2
Then we can use our knowledge and do
x^2 +4.
We have to multiple the two by two and then x because that is a rule in
(a + b) ^2
=
a^2 + b^2 + 2ba
So we end up with x^2 + 4x +4
Find the surface area of the cone with a diameter of 12 centimeters and a slant height of
85 millimeters.
Please answer due in 20 minutes
Answer:
lateral surface area is 160.14 square cm.
Total surface area is 273.16 square cm
Step-by-step explanation:
Lateral surface area of cone is given by [tex]\pi rl[/tex]
where r is radius of cone
and l is slant height of cone.
l = 85 millimetres
we know that 10 millimetres is equal to 1 cm
Thus 85 millimetres is equal to 8.5 cm
Thus slant height(l) in cm is 8.5[tex]\pi rl\\=>\pi 6*8.5\\=> 3.14*51\\=>160.14[/tex]
we will use value of [tex]\pi[/tex] as 3.14
Diameter of cone = 12 cm
we know that radius is equal to half of Diameter
radius of given cone = 1/2 *Diameter = 1/2 * 12 = 6 cm.
Thus lateral surface area of cone is given by
[tex]\pi rl\\=>3.14*6*8.5\\=>153[/tex]
Thus, lateral surface area is 160.14 square cm.
Area of base of cone will be area of circular base
area of circle is given by [tex]\pi r^2[/tex]
Thus area of base is given below
[tex]\pi r^2\\=>3.14*6^2\\=>113.04[/tex]
area of base is 113.04 square cm
Total surface area of cone is sum of area of base and lateral surface area
Total surface area = 160.14+113.04 = 273.16 square cm.

Answer:
A.
Step-by-step explanation:
Given that point P partitions a directed line segment from A to B into the ratio 3:4, we are to determine how close P is to either A or B.
To do this, we take an example.
Let the length of line segment AB be 14 Units.
Since P divides AB in the ratio 3:4
Length of AP[tex]=\frac{3}{7}X14=6 \:units[/tex]Length of PB[tex]=\frac{4}{7}X14=8 \:units[/tex]Therefore, from the above, we can conclude that P will be closer to A as its distance from A is shorter than its distance from B.
The correct option is A.
Answer:
Point P partitions the directed line segment from A to B into the ratio 3:4. Will P be closer to A or B? Why?
A number line goes from point A to point B. A line is drawn from point A to point B.
Right Answer A.) P will be closer to A because it will be Three-sevenths the distance from A to B.
Wrong Answer B.) P will be closer to A because it will be Four-sevenths the distance from A to B.
Wrong Answer C.) P will be closer to B because it will be Three-sevenths the distance from B to A.
Wrong Answer D.) P will be closer to B because it will be Four-sevenths the distance from B to A.

Raman have 72.75 M long string he cut the string in certain species of equal length if one piece is 14.55 M long how many pieces are cut out of from the rope
Answer:
5
Step-by-step explanation:
Raman have 72.75 M long string and he cut the string in pieces of equal length of 14.55 M long .
To find how many pieces he cut, we simply divide the length of the original piece of string by the length of the cut piece of string.
That is:
72.75 / 14.55 = 5
He can cut 5 pieces of string.
Which system of equations has one solution?
On a coordinate plane, 2 lines intersect at one point.
On a coordinate plane, 2 lines are parallel to each other.
On a coordinate plane, a line has a positive slope.
Answer:
A
Step-by-step explanation:
Hence, the option (A) is the correct answer i.e., On a coordinate plane, two lines intersect at one point
What are the one solution ?
One Solution Equation is when an equation has only one solution. This means that when you solve an equation, the variable can only be subsituted by one number to make an equation true.
So, when the two lines passes and intersect at one point it forms one solution so that is why option (A) is correct i.e., On a coordinate plane, two lines intersect at one point.
Hence, the option (A) is the correct answer i.e., On a coordinate plane, two lines intersect at one point

“And what, after all, is the matter on hand?” I asked.
“Why, I will tell you,” replied the Prefect, as he gave a long, steady, and contemplative puff, and settled himself in his chair. “I will tell you in a few words; but, before I begin, let me caution you that this is an affair demanding the greatest secrecy, and that I should most probably lose the position I now hold, were it known that I confided it to any one.
“Proceed,” said I.

Two joggers run 8 miles north and then 5 miles west. What is the shortest distance , to the nearest tenth of a mile, they must travel to return to their starting point?
PLSS HELP EXTRA POINTS, WILL GIVE BRANLIEST!!
Answer:
9.4 miles
Step-by-step explanation:
We can assume that if these joggers run 8 miles north, consecutively 5 miles west, these lengths form legs of a right angle triangle, from which we have to determine the hypotenuse of the triangle provided it would lead to the shortest route possible;
Knowing this is a right angle triangle, let us apply Pythagorean Theorem to solve for the length of this hypotenuse, which we can assign as x;
8^2 + 5^2 = x^2 ⇒ square 8 and 5,
64 + 25 = x^2 ⇒ Combine like terms,
x^2 = 89 ⇒ Take square root on either side
Solution; Shortest Distance ⇒ length of 9.4 miles

The dimensions of a CD case are 14.2cm by 12.5cm. Each case is approxiomately 1cm deep. What would be the volume of this stack of 17 cd cases to the nearest tenth?
Answer:
3017.5 cm³
Step-by-step explanation:
The volume of a rectangular prism is V = l × w × h
Here the length is 14.2, the width is 12.5, and the height is 1
Plugging these into our formula we get V = (14.2)(12.5)(1) = 177.5 cm³
Since there are 17 CD cases stacked on top of each other, we will multiply our number by 17 which gives us (177.5)(17) = 3017.5 cm³

By what number do you multiply the radius of a circle to double its area? Show the process to get the answer.
Answer:
Area of circle = πr²
New doubled area = πR² ( r ≠ R )
As it is double of older area :
πR² = 2πr²
R² = 2r²
R = √2r
Thus we have to multiply the radius to √2 to double its area
In the derivation of the quadratic formula by completing the square, the equation is created by forming a perfect square trinomial. What is the result of applying the square root property of equality to this equation?
Answer:
The result is
x + b/2a= ±√[(b² - 4ac)/2a]
Step-by-step explanation:
In the derivation of the quadratic formula by completing the square, the equation is created by forming a perfect square trinomial
ax² + bx + c = 0
x² + (b/a)x + c/a = 0
x² + 2(b/2a)x + b²/4a² - b²/4a² + c/a = 0
(x + b/2a)² - b²/4a² + c/a = 0
(x + b/2a)² = b²/4a² - c/a
(x + b/2a)² = (b² - 4ac)/2a
Apply square roots to both sides
x + b/2a= ±√[(b² - 4ac)/2a]
it can also be explained as B on edg :)
What is the measure of the missing angle?
Answer:
answer is 60
Step-by-step explanation:
because if the angle is 60 degrees anywhere in the triangle means its an equilateral triangle making all the angles 60 degrees
Answer:
60 degrees
Step-by-step explanation:
Every Triangle has an angle of 180 degrees
so if we add all of the written angles which is 25 + 35 + 60 = 120
we take 180 degrees and subtract it with the previous answer (120)
180 - 120 = 60
Therefore it is 60 degrees

Mums are plants that bloom in the fall.
Which statement describes the photoperiodism of mums?
They bloom when the days are longer.
O They bloom when the nights are longer.
O They bloom when the temperatures are warmer.
They bloom when the temperatures are colder.
My reasoning is the mention of PHOTOPERIODISM. Photoperiodism means the reaction to length of a day or night cycle, since fall is the beginning of shorter days and longer nights, it is only reasonable that the answer is that THey bloom when the nights are longer.

graph:y-3=1/2(x+2)
----------------------------------------------------------
Answer:
x intercept = -0.25
y intercept = 4
Step-by-step explanation:
1.- remove parenthesis
y-3 = 1/2x +1
2.- adjust to equal y
y = 1/2x +1 +3
y = 1/2x +4
3.- guess values for x to try in the simplified equation.
x = -0.25 | y = 0
x = 0 | y = 4
x = 2 | y = 5
x = -2 | y = 3
x = 4 | y = 6
x = -4 | y = 2

There are 15 dogs, 22 cats, and 4 rabbits at a shelter. Each dog needs a collar, bowl, and toy. Each cat needs a collar, bowl and 2 toys. Each rabbit needs a bowl. How many total toys will the shelter need?
Answer:
137 toys
Step-by-step explanation:
You take the number of dogs = 15
and how many things each dog needs = a collar, bowl, and toy
and you multiply 15 by three to get the number of collars, bowls, and toys each dog needs. Then repeat this process and add all of your answers
Dog = 60
Cat = 88
Rabbit = 4
88 + 60 + 4 = 137
(If the collar, and bowls don't count as toys then just message me and I will redo the math for you.)
