Step-by-step explanation:
(x-9) is a factor
x-9 =0 so x=9
now we plug in 9 for x and see which polynomial gives us remainder 0
A. x^2 - 6x +9 = 9^2 - 6(9) + 9 = 36
Remainder = 36 so (x-9) is not a factor
B) x^2 + 16x + 63= 9^2 + 16(9) + 63 = 288
Remainder =288 so (x-9) is not a factor
C) x^2 + 14x + 45= 9^2 + 14(9) + 45 = 252
Remainder = 252 so (x-9) is not a factor
D) x^2 - 12x + 27= 9^2 -12(9) + 27 = 0
Remainder = 0 so (x-9) is a factor

The surface area of a sphere is A = 4π R²
The volume of a sphere is V = (4/3) ( π) (R³)
The ratio of (surface area) to (volume) is
4 π R² / (4/3) (π) (R³)
Divide top and bottom by 4π : R² / (1/3) (R³)
Multiply top and bottom by 3: 3 R² / R³
Divide top and bottom by R² : 3 / R .

Answer:
if red = 1 white = 4/3 or 1 1/3
if white = 1 red = 3/4
if red = 4 white = = 16/3 = 5 1/3
if white = 5 red = 15/4 = 3 3/4
Step-by-step explanation:
white 4
--------= ---------
red 3
if red = 1
white 4
--------= ---------
1 3
using cross products
white *3 = 4*1
divide by 3
white = 4/3
if white = 1
1 4
--------= ---------
red 3
using cross products
3*1 = 4* red
divide by 4
3/4 = red
if red = 4
white 4
--------= ---------
4 3
using cross products
white *3 = 4*4
white *3 = 16
divide by 3
white = 16/3 = 5 1/3
if white = 5

--------= ---------
red 3
using cross products
3*5 = 4* red
15 = 4 * red
divide by 4
15/4 = red
3 3/4 = red
