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.
9 = c(c - 8)
9 = c² - 8c
c² - 8c - 9 = 0
c² + c - 9c - 9 = 0
c(c + 1) -9 (c + 1) = 0
(c+1)(c-9) = 0
c = -1 or 9
In short, Your Answers would be -1 and 9
Hope this helps!
Answer:

Step-by-step explanation:
We can look at the terms one by one. We know that to get 5 to 1 we must add -4 so the first term is:

For the x term to go from -3 to -5 we must add -2, so the second term is

Lastly, to go from -9 to 6 we must add 15. The final polynomial added is:
