Factor the polynomial 3x + 6 if the polynomial cannot be factored, write prime. place a space between each term in your answer . squared terms should be expressed in the form x^2 without spaces. example: 5x^{2}(3x-2) should be expressed as 5x^2(3x - 2)

5x^2(3x-2)

5x^2 multipled 3x -5x^2 multipled -2

15x^2-10

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
