Answer:
a)
The point that is equidistant to all sides of a triangle is called the incenter.
The incenter is located at the intersection of bisectors of the interior angles of a triangle.
b)
The point that is equidistant to all vertices of a triangle is called the circumcenter.
The circumcenter is located at the intersection of perpendicular bisectors of the sides of a triangle.
c)
See the attachment
The blue lines and their intersection shows the incenter.
The red lines and their intersection shows the circumcenter.
As we see the red point- the circumcenter is closer to vertex B.

Question 1Let number of adult tickets - x, student tickets - yRequired equations:
x + y = 87.25x + 5.50y = 52.75Solve by substitution x = 8 - y
7.25(8 - y) + 5.50y = 52.7558 - 7.25y + 5.50y = 52.751.75y = 5.25y = 5.25/1.75y = 3Find x:

Answer:
19.6375 mm^2
Step-by-step explanation:
Given data
Diameter = 5mm
Radius= 5/2= 2.5mm
The expression for the area
A=πr^2
Substitute
A=3.142*2.5^2
A=3.142*6.25
A=19.6375 mm^2

A ladder is leaning against a building so that the distance from the ground to the top of the ladder is 3 feet less than the length of the ladder. Find the length of the ladder if the distance from the bottom of the ladder to the building is 9 feet.
Answer:
15 ft
Step-by-step explanation:
This is another classic case of Pythagoras theorem. To start with, let's assume that the length of the ladder we're looking for is x
We're told that the height of the building the ladder is leaning on is, x - 3
Also we're told that the distance at an adjacent from the ladder is 9 ft.
If we use Pythagoras theorem, we have
x² = (x - 3)² + 9²
x² = x² - 6x + 9 + 81
On rearranging, we have
x² - x² = -6x + 90
6x = 90
x = 90 / 6
x = 15 ft
Therefore, the length of the ladder is found to be 15 ft

The solution of the given equation is x = 2.1
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, an equation, 3ˣ = 10, we need to find the solution of it,
So, solving for x,
3ˣ = 10
Taking log both sides,
㏒ 3ˣ = ㏒ 10
Since, ㏒ aⁿ = n ㏒ a
Therefore,
x ㏒ 3 = ㏒ 10
x = ㏒ 10 / ㏒ 3
x = 1/0.477
x = 2.095
x ≈ 2.1
Hence, the solution of the given equation is x = 2.1

Would give more pts if i had them
Answer:
1) They forgot to multiply 2 times (2x+5)
2) x-2 is not equal to -(x+2).
3) The correct expression is [tex]x-1-1+2x=1-3x[/tex]
4) The correct way is [tex]4(2x+3)=3(1-3x)[/tex]
Step-by-step explanation:
1) In this case they forgot to multiply 2 times (2x+5). Let's recall we need to multiply (2x+5) to all terms of the equation.
2) Here, x-2 is not equal to -(x+2). If we see -(x+2) = -x-2 using the distributive property.
3) After multiplying by (3x-2) we will have:
[tex]x-1-(1-2x)=1-3x[/tex]
Apply the distributive property again, we will have:
[tex]x-1-1+2x=1-3x[/tex]
So the correct term is 2x not -2x.
4) When we multiply by (1-3x)(2x+3) on each side of the equation, we will have something like this:
[tex]\frac{4(1-3x)(2x+3)}{(1-3x)}=\frac{3(1-3x)(2x+3)}{(2x+3)}[/tex]
If we see we can simplify the same terms on each side of the equation.
[tex]4(2x+3)=3(1-3x)[/tex]
This is the correct way to do this.
I hope it helps you!
