Answer:
Step-by-step explanation:
surface area of sphere=a
4pir^2=a
r^2=a/4p
r=root(a/4pi)
if radius is doubled
r1=2root(a/4pi)
r1^2=4(a/4pi)
a/a1=(4pia/4pi)/(4pi 4a/4pi)=1/4
so a is increased by 4 times

Answer:
The answer is B)
Step-by-step explanation:
Step 1: First we have to factorize the each rational expressions.
÷
= ÷
Now we can cancel out (2x + 3) and (2x -1) since they are common factor both in the numerator and the denominator, so we get
= ÷
Step 2: If we have fraction over fraction, we can flip the second fraction and multiply.
= x
Now we can cancel out (3x + 2), so we get
=
Thefore, the answer is B.
