Answers
a^2+b^2=c^2
c=hypotenuse
a^2+b^2=20^2=400
if the permiter is 42 then
p=hypotonuse+side+side
42=20+side+side
subtract 20 from both sides
22=side+side
a+b=22
subtract b from both sides
a=22-b
subsitute for a in equation below
a+2+b^2=c^2
(22-b)^2+b^2=400
b^2-44x+484+b^2=400
2b^2-44x+484=400
divide both sides by 2
b^2-22x+242=200
subtract 200 from both sides
b^2-22x+42=0
factor
(b+/-number)(b+/-number)
to find the numbers, find which 2 number multiply to 42 and add to get -22
the numbers must be neative since same signs multiplied=positive and negative+negative=negative
(b-number)(b-number)
facrors of 42=2,3,6,7,14,21
2,21
3,14

it's hard to find the number, but the numbers are -19.8882 and -2.11181
(b-19.8882)(b-2.11181)=0
if xy=0 then assume that x and y=0
b-19.8882=0
add 19.8882 to both sides
b=19.8882
b-2.11181=0
add 2.11181 to both sides
b=2.11181
the side legnths are 19.8882 units and 2.11181 units

Answer: is the inequality and x is the number of seats in each row in the ground floor.
Step-by-step explanation:
Since, The total number of people may attend = People in the balcony + People in the ground floor.
And, According to the question, Number of the people in the balcony = 120
Now, Let x represents the number of the seats in the ground floor,
While y represents total number of people.
And, again according to the question,
There are 32 rows on the ground floor,
Therefore, the number of the people in the ground floor = 32 x
y = 120 + 32 x
But, the total number of the people must be not more than 720.
Therefore,
⇒
⇒
⇒
Where x is the number of seats in the ground floor.
32*x < 600
x < 18.75
because of x represents the number of seats in each row, it has to be a natural number -- whole. so x=18 is the max number of seats in each row and x < 18.75 is the desired inequality.
