he change 3/4 instead of 5/7
f(x) = 3x²
g(x) = 4x³ + 1
f(g(x)) = 3.(4x³ + 1)²
As we know
(a + b)² = a² + 2.a.b + b²
So,
(4x³ + 1) = (4x³)² + 2.4x³.1 + 1² = 
f(g(x)) = 3.(
)
The degree is the maximum exponent, so, 6.
Answer:
The no. of subscribers of the magazine after 5 years is = 55713

For finding total distance , we will find distances and then add them
He runs 12 km/hr for 5 minutes
First distance:
speed =12 kh/hr
time=5 minutes
we can change into hour


now, we can plug values


second distance:
speed =17 kh/hr
time=8 minutes
we can change into hour


now, we can plug values


third distance:
speed =6 kh/hr
time=2 minutes
we can change into hour


now, we can plug values


now, we can find total distance



so,
total distance is 3.46667 km...........Answer
A centimetre is the most appropriate unit
