Can you provide a picture?
The answer is D. Group =2
A)We have been given →
Hieght of trough = 5m
length of trough = 6m
Breadth of trough = 4m
so , As the top is opened for feeding animals.
Area of base = length× Breadth
= (6×4) m²
= 24 m²
Area of Front and back face = Hieght × length
= (5×6) m²
= 30m²
Area of side faces = hieght × Breadth
= (5×4) m²
= 20 m²

B)Total Surface area of trough will be given by formula - 2(lb+bh+hl)
= 2{(6×4)+(4×5)+(5×6)}
= 2{24+20+30}
= 2×74
= 148 m²
As we have been told top is open , so we will deduct top from Total surface Area to obtain Surface area →
(148-24) m²
(Area of top will be same as base area , that is 24m² as we have solved in A)
= 124m²
Answer→ Surface area of trough is 124m²

Answer:
Jose's solution is not correct, the auditorium has 
rows
Step-by-step explanation:
we have
where
f(x)------> is the total number of seats in an auditorium
x----> represents the number of rows
How many rows are there in the auditorium if it has a total of 416 seats?
Find the value of x for f(x)=416 seats
substitute the value of f(x) in the equation
Using a graphing calculator
The values of x are 
The solution is
x=16 rows because the number of rows can not be a negative number
Answer:
what is the bottom one
you can do
72+y + the bottom= 180
(sum of all angles of triangle is 180)
