Lines A and B are parallel to each other. Lines B and E are perpendicular to each other.
The answer is B. Hope this helps!(:
The surface area of a sphere is

and if the original S.A was is enlarged to have it 9 times greater, the radius would be multiplied by 3 or roughly 2.99626 rounded off to 3.0.
For example, let us assign values.
Let A=90
A= 90*9 = 810

and

the first r is 2.68 and the second r is 8.03
then,

or rounded off to 3.
Answer:
x+y=9....(i)
2x-6=y....(ii)
then putting the value of y in (i) eqn
x+2x-6=9
3x=15
x=5
Now, putting the value of x in (ii) eqn
then 2*5- 6 =4
Step-by-step explanation:
SO the value of x is 5 and y is 4
