The prime factorization of K is: K = 3·5·7. List all the composite factors of K.

k=105

Step-by-step explanation:

3,35,5,21,7,15,

15, 21 and 35.

Step-by-step explanation:

They are 3*5 , 3*7 and 5*7.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
