The given function is
Here represents the number of rows.
represents the total number of seats in the auditorium.
Now the total seats in the auditorium are 416.
So
Dividing all terms by 2 we get
Subtracting 208 from both sides
Factoring we get
(x-16)(x+13)=0
Using Zero product rule
x - 16= 0 or x+13=0
x= 16 or x = -13
But as x cannot be negative
So x = 16
There are 16 rows in the auditorium if it has a total of 416 seats.
Surface of a cube=S(x)
S(x)=6x²
S(2 m)=6(2 m)²=6(4 m²)=24 m²
The surface of this cube is 24 m².
Volume of a cube=V(x)
V(x)=x³
V(2 m)=(2 m)³=8 m³
The volume of this cube is 8 m³.
The answer to this is A and D. A and D are both rational because they contain repeating numbers.
B) could've been the answer but it doesn't show any repeating numbers
C) Doesn't have a repeating number.
So A and D are the answers. (if there is only one option for this answer then D should be the answer)
Hoped this helped :)
Have a great day
