I will do the first one only. The second question is done the same way.
Replace every x you see in the function with 2b and do the math.
f(x) = x^2 + 2x + 1
Let x = 2b
f(2b) = (2b)^2 + 2(2b) + 1
f(2b) = 4b^2 + 4b + 1
Did you follow? That's all there is to it.
71 is the answer. If you round it, it would be 70.

<u>Answer:</u>
Option(b) = 10
The Number 6 in the thousands place is 10 times bigger than the Number 6 in the hundreds place
<u>Explanation:</u>
We are given the value recorded = 16,652
Now the Number 6 in hundreds place means it is equal to 600 and the Number 6 in thousands place means that it is = 6000
from the given value 6 in hundreds place = 652 and
that in thousands place = 6520 ,
so the six in thousands place is obtained by multiplying 10 with the 6 in hundreds place hence the latter is 10 times bigger than the former.
