Answer:
Step-by-step explanation:
to find the surface area we need to find the followng areas:
- area of a triangle and multiply it by 4 (because there are 4 triangles)
And once we have those areas, we add them to find the surface area.
Area of the square:
the formula to find the area of a square is:
where 
is the length of the side: 
thus the area of the square is:
Area of the triangles:
the are of 1 triangle is given by
where 
is the base of the triangle: 
(the base of the triangle is the side of the square)
and 
is the height of the triangle: 
thus, the area of 1 triangle is:
the area of the 4 triangles is (we multiply by 4):
finally we add the area of the square and the area of the 4 triangles to find the total surface area:
So hexagon is 6 sides and 6 angles
it can have a max of 2 right angles
if you make an irregular hexagon with one of the lines going into the figure then the answer is 4
if you have all the lines outside of the hexagon then the max is 2

Answer:
A.
Amir's equation : 5.50 p + 55.99 =200
Edward's equation : 5.50 p+ 55.99 ≤ 200
B. Amir's equation presents the situation best because it gives the cost of the part as per the budget. Edward's equation gives room for lesser amounts to be used in case p< 26.
Step-by-step explanation:
The budget is $200
The party room charges $55.99
The charge per person is $5.50
Letting p =number of people that can attend the party, then
A.
Equation for cost that Amir use is;
$5.50*p + $55.99 = $200
5.50 p + 55.99 =200
5.50 p = 200-55.99
5.50 p =144.01
p= 144.01/5.50 = 26 -------Amir's equation will also give the number of people that can attend the party with the budget of $200
For Edward's case
$5.50 p +$55.99 ≤ $200
5.50 p+ 55.99 ≤ 200
5.50 p ≤ 200-55.99
5.50 p ≤ 144.01
p ≤ 144.01/5.50
p ≤ 26
Edward's inequality suggests that for the budget of $200 , 26 or less people can attend the party.
B. Amir's equation presents the situation best because it gives the cost of the part as per the budget. Edward's equation gives room for lesser amounts to be used in case p< 26.
